[Q]: Passage: Present-day Christian religious bodies known for conducting their worship services without musical accompaniment include some Presbyterian churches devoted to the regulative principle of worship, Old Regular Baptists, Primitive Baptists, Plymouth Brethren, Churches of Christ, the Old German Baptist Brethren, Doukhobors the Byzantine Rite and the Amish, Old Order Mennonites and Conservative Mennonites. Certain high church services and other musical events in liturgical churches (such as the Roman Catholic Mass and the Lutheran Divine Service) may be a cappella, a practice remaining from apostolic times. Many Mennonites also conduct some or all of their services without instruments. Sacred Harp, a type of folk music, is an a cappella style of religious singing with shape notes, usually sung at singing conventions.

[Q]: Passage: Turner Classic Movies essentially operates as a commercial-free service, with the only advertisements on the network being shown between features – which advertise TCM products, network promotions for upcoming special programs and the original trailers for films that are scheduled to be broadcast on TCM (particularly those that will air during the primetime hours), and featurettes about classic film actors and actresses. In addition to this, extended breaks between features are filled with theatrically released movie trailers and classic short subjects – from series such as The Passing Parade, Crime Does Not Pay, Pete Smith Specialties, and Robert Benchley – under the banner name TCM Extras (formerly One Reel Wonders). In 2007, some of the short films featured on TCM were made available for streaming on TCM's website. Partly to allow these interstitials, Turner Classic Movies schedules its feature films either at the top of the hour or at :15, :30 or :45 minutes past the hour, instead of in timeslots of varying five-minute increments.
[A]: What were TCM products previously known as?


[Q]: Passage: Music, photos and videos can be played from standard USB mass storage devices, Xbox 360 proprietary storage devices (such as memory cards or Xbox 360 hard drives), and servers or computers with Windows Media Center or Windows XP with Service pack 2 or higher within the local-area network in streaming mode. As the Xbox 360 uses a modified version of the UPnP AV protocol, some alternative UPnP servers such as uShare (part of the GeeXboX project) and MythTV can also stream media to the Xbox 360, allowing for similar functionality from non-Windows servers. This is possible with video files up to HD-resolution and with several codecs (MPEG-2, MPEG-4, WMV) and container formats (WMV, MOV, TS).
