 Trying to watch a previously recorded stream or live-tv from an IPTV
 channel produces very choppy playback with lots of glitches/artifacts.

 Channel URL correspond to rtp:// multicast, using udp:// in "url" column
 in iptv_channel (set by hand, since (that's another bug), mythtv doesn't
 populates it when scanning the .m3u file for channels).

 The same stream, recorded by mythbackend, can be played from file without
 problems with mplayer and vlc. Trying to play the same file with ffplay
 causes also glitches/choppy image and, at some point, ffplay
 aborts/segfaults.

 System is mythbuntu 12.04. Output of lsb_release -a:
 No LSB modules are available.
 Distributor ID: Ubuntu
 Description:    Ubuntu 12.04.3 LTS
 Release:        12.04
 Codename:       precise

 HW: Xtreamer ultra, nvidia graphics card & propietary drivers.

 Using VDPAU for video playback.

 I'm also attaching a 1min sample of the stream recorded and the output for
 "mythavtest --loglevel debug -v all"

 thanks in advance,
 Jose
