Question: Is RealPlayer compatible with this and easy to download videos to?
Document: Bought this for the wife for Christmas. It is a good step up from the old MP3 player. The screen is small, but for the price you get to listen to MP3, can watch videos and download pictures. It is realitively easy to use. I may have to get one for myself!
I was excited to receive the Coby, and liked the look and feel of this MP3. I was disappointed that the  MP3 did not hook into my Windows Media player, to download my existing media music files. I have used other MP3 players that are compatible to Windows. However, the coby is able to access hard drive music and with this I can move existing files over to a hard drive folder. Otherwise, liked the product.
I had purchased this to download and listen to audio books checked out from my local library using a program the library supplies called Overdrive. This Coby mp3 player is not compatible with this program. I checked with the Coby company and learned that the unit will not play "protected media". So it may be a fine product for other purposes, but don't get it for library downloads which use Overdrive. It did seem to work with files using NetLibrary.
Although the device is sleek, the instructions are such that I am unable to download videos to the desired xx.mtv format. The instruction manual, under the section "video mode ", refers me to a section called "movie conversion". There is no such section in the manual or on the web, including their FAQ section. In their "movie manager" I have attempted to convert xx.flv and xx.mpg formats.
I'm sorry this thing didn't work our. I so looked forward to listening to my 300 songs on an MP3 player on the go or while traveling to Dallas. I Received my first Coby MP620 4 GB Video MP3 Player with FM Radio (Red) about a week ago and after I Synced all my songs to the unit all I could play was about 8 songs by Hank Williams,  The pictures I downloaded lasted about 8 hours , then they were gone,  it would't even download/sync any videos.
This is the first MP3 player and am completely happy with it, there is only one issue.This player is not compatible with a MacBook Pro. So down loading to this palyer is not easy to do.
This  is a great product. I would have easily paid double for it if I where given the chance to give it a trial run. Syncing and removing music/picture/video files is extremely easy, and you dont have to worry about having compatible software. TOTALLY WORTH BUYING.
Gave these to my boys for Christmas. They really like them, except for the fact that we haven't been able to upload any videos yet. The sound is great and it's easy to operate.
easy navigation, long battery life. does seem long to refresh after adding or removing files. good for sound files. videos aren't worth it.
It looks good, the controls are easy to use and the price was amazing. The monitor is extremely tiny for watching videos, but it fits in your pocket! 4GB holds a couple of full-length movies or a nearly-infinite amount of music.
Answer: I don't know about RealPlayer, I use the USB cable to transfer music to my Coby.  And mine is the 8g, not the 4--but if they are the same except for memory, it's a poor choice for video.  The screen is smaller than my year-old Sansa, and the player only handles one odd video format, ".mtv"  So I wouldn't recommend this for video.  Good MP3/radio, though.
