     Type:  enhancement  |      Status:  new

 Severity:  medium       |  
 If you channel change too quickly with 0.20-fixes it is possible to end up
 with jerky video on playback that can only be fixed by restarting live tv.
 This has been fixed in the main SVN trunk. The OpenMedia myPVR build has
 included the attached changesets backported from trunk for several months
 which have resolved the issues.

 The nice to have changesets also appear to reduce the occurrences of
 "Error was encountered while displaying video" dramatically.

 Must have

     * changeset:11324 - Modifies WarpTimecode
     * changeset:11616 - Sets the proper bitrate in the RingBuffer after it
 is reset by an OpenFile
     * changeset:11834 - RingBuffer adaptive sizing

 Nice to have's

     * changeset:12550 - Fixes a ringbuffer switching race condition.
     * changeset:12675 - RingBuffer race condition
     * changeset:12750 - MPEG decoder start optimisations
