Downloads: Multiple downloading threads at the same time to make performance better?:

This row shows whether enqueued podcasts can be downloaded in parallel. The point in parallel downloading is as follows:

-	Some servers serve podcasts considerably slower than your local Internet connection. Say you have a 2 Mbps connection, while the server you’re currently downloading podcasts is only capable of serving a podcast at 500 kbps. This means 1.5 Mbps of your Internet connection remains unused.

-	You may want to quickly download something while another download is in progress. For example, let’s assume you’re downloading a huge podcast when you notice there’s another, interesting one you’d like to listen to as soon as possible. In a single-threaded (simple) app, you would either need to cancel the current download(s) to quickly queue the new clip as the first one to download. In a more advanced multithreaded app, you just start the download and it downloads (albeit a bit slower because the bandwidth available may be divided up between the current downloads), without further ado.

Progress bar (or any way to see what has already been downloaded): better apps have some kind of a visual feedback showing how many bytes (and/or percent) of a given podcast (and, preferably, all the queued podcasts) have already been downloaded.

Streaming (playback without downloading the entire enclosure (first)) Supported? : better players allow for streaming – that is, playback without downloading the entire enclosure first. Note that the built-in WMP doesn’t support this; CorePlayer does.

If streamed, random positioning supported?: there are two approaches to streaming – one that allows for quickly fast forwarding into still not downloaded parts of the podcast (that is, allows for really free random access, independent of what has already been downloaded) and the simpler one that doesn’t. Naturally, the former is preferred.

Here, n/a, naturally, shows the given app isn’t at all able to stream.

Feed input (in addition to direct address entering, which is supported by all): OPML import / sync?: There are several ways of making podcast/catcher apps aware of the feeds you’d like to subscribe to. In addition to by directly entering their URL’s, one-by-one, the most important way of importing them is via OPML files.

Note that several of the apps also support exporting into OPML files of your current subscriptions, which makes it easier to transfer your current subscriptions to another (OPML import-capable) podcatcher/caster.

M3U / PLS support?: some apps also allow for mass-importing feed URL’s via the well-known M3U and/or PLS playlist files. (See for example THIS for more info on these formats.)

Pre-defined, built-in library?: many of these apps have some kind of access to predefined, online libraries already offering feeds you can subscribe to.

Online search?: there are several services allowing for feed lookup based on their names. Some of the handset apps have interfaces to directly access these services.

Generic HTML page parsing if unsure about the exact feed URL?: (very) few apps allow for parsing generic HTML pages to find feed URL’s in them. (This is how most desktop browsers and Opera Mini work when they display a “This page has RSS feeds in it” type of message.)

Online, web-based, synchronizable and/or readable account?: one of the best capabilities some of these apps offer is an online account allowing for either account management (importing / deleting etc. feeds, sharing them with your friends, the community etc.) or on-line article reading via any Web browser – or both.

The former greatly simplifies subscribing to feeds (and deploying the same set of feeds to other, OPML importing-capable podcasters later).

Built-in player (if any): AVRCP: while the majority of these apps rely on external players to play even the most basic and widely used podcasting file formats like MP3, some of them have a built-in player to play them back. It’s the limitations, capabilities, CPU (and, consequently, battery) usage of these built-in players that this group is all about.

The first test in this group, AVRCP, discusses whether Bluetooth remote control, AVRCP, is supported by the player (if any). Naturally, as with most of the entries in this group, n/a means there’s no built-in player in the app at all.

CPU usage?: The CPU usage of multimedia players is of extreme importance when it comes to maximizing battery life. This is why I’ve made some extensive tests to find out how these apps behave in this regard. Please also see THIS for more info on the well-established players.

Remembers last position (resume-capable)? And, even better, auto bookmark-capable?: with sometimes lengthy podcasts, it’s essential for a player to be able to resume playback after restarting (simple resume) or even switching to another and, then, returning to the same podcast (more advanced bookmarking capability; now, storing a “last playback position” associated with each podcast file, not just globally for the last played one).

Positioning (with already-local playback); + stands for external players with podcatcher apps without a built-in player: it’s also essential for a podcast playback application to be able to randomly position inside the already-local podcast. Note that this has nothing to do with the positioning capabilities of still-downloading and/or streamed apps, which was elaborated upon earlier.

If it does have a player, can you still use an external one?: almost all the built-in players are definitely inferior (buth CPU usage- and capabilities-wise) to those offered by other, third-party players. Therefore, particularly with podcaster applications having a low-quality player, it’s essential to be able to configure it to be able to invoke an external multimedia player to play back any multimedia content.

Channel / individual song image support: Generic channel image displayed?: This group elaborates on whether generic (non-podcast-specific) channel images and podcast-specific, inline images are supported.

The first test, “Generic channel image displayed?”, shows the podcaster app is able to display the generic image associated with a channel. This is in no way essential, just cool to have and makes it easier to easily spot a feed, particularly if there are more than a handful of them.

Album art / article display? :

Note that, with external players, this will only players that do support embedded artwork in individual podcasts; that is, NOT the built-in Windows Media Player Mobile in Windows Mobile. See the first chart HERE for more info on this question and the compatible apps.

Mass playback / delete operations: Mass playback in a given channel?: this mass operation-specific group elaborates on operations best done in one step instead of doing the same separately for each and every headline / podcast – that is, using mass operations.

The first of the tests, “Mass playback in a given channel?”, elaborates on whether the podcasts of a given channel (feed) can be played back in order without having to manually intervene (that is, start the next one when the previous is finished). This is of extreme importance with shorter clips you’d like to see. Just a real-world example: during my last 10-hour-long bus trip, I’ve watched almost all the episodes of X-Play. These podcasts are, in general, some 2…5 minutes long. As the client (the otherwise great NewsBreak) doesn’t support mass playback, it was quite a nuisance to always having to switch back to NewsBreak (from CorePlayer playing the video) and tap (with my finger) on the next feed’s “Play” icon.

With podcaster apps capable of mass playback (either in a given channel/feed or globally, with all available podcasts), you don’t need to constantly switch back to the podcaster app to start the playback of the next podcast.

Incidentally, behind the scenes, mass playback is accomplished by using playback (m3u / pls / asx files). This is how podcaster apps instruct external players to be aware of more than one playlist items. Also, this is why some of the podcaster apps (for example, Egress) explicitly refer to creating playlist files upon downloading.

Mass playback globally (not just in one channel, but all the new enclosures)?: while the previous row discussed in-feed mass playback (without human intervention), this one refers to playing back all the clips globally, originating from all feeds, not just one. Unfortunately, as with the feed-only playback, very few podcasters support this.
