hue problems when playing back transcoded videos on PVR-350

HD captures that are transcoded and played back using my PVR-350 (w/ivtv-0.6.2) have hue problems (i.e. blue faces) as of SVN 10992. Only transcoded videos are affected by the color problems. Recordings that are captured from the PVR-350 and then played back using the 350's decoder are fine. Also, MythVideo? files play back fine with mplayer.

Attached is the output of "mythfrontend -v playback" that was generated while playing back one of the transcoded files.

I concur that this is a problem. To give some more information:

For me, it happens with video recorded at 720 x 480 and then transcoded at the same size. Only fbdev is affected. These same videos play back fine on another instance of X, using an Nvidia card.

Furthermore, attempting to use the Xv picture controls to adjust hue fails. The slider goes to -1 and then refuses to move in either direction.

Correction: change "fbdev" to "ivtvdev" in the previous message.
