Fixes
Video playback freezing/black screen
Loss of trick play in a currently recording program. When this occured, the program recording would corrupt and would be unplaybe.
Canceled programs rescheduling. (Due to higher priority shows being canceled in conflict resolution dialogs, the background process would reschedule the higher priority show)
Find By Channel, would return results on "hidden" channels. This is NOT related to Favorites or Channels you receive.
Recording the same show, on channels with the same channel number, would result in a corrupted recording. (Example: Trying to record the show from the HD Local and the SD Local at the same time)
Adding extensions to a recording, via UPDATE... would not trigger conflicts.
Caller ID - "Call your service provider", should no longer appear if you are a Caller-Id subscriber.

Known Issues with release
Pixelization During FF/RW functions. Noticeable primariy in 1080i/720p MPEG4 recordings, while FF/RW the video play pixelizes. This is due to updates with the MPEG4 code (which was changed to address other issues), the pixelizing will be corrected in a future release.
Notes
The black screen recordings should now be corrected. However, programs recorded on previous versions of the software will still have the problem.
