[mythtv] Found a severe decoding bug in mythffplay

[Mark Robinson]

Hey Guys,

I just upgraded to MythTV-0.25-fixes and I've found a rather serious
decoding bug.

If you use mythffplay to play a video file then the blue and red color
channels will be reversed.

If I play the video on a different machine, it works fine.
If I play the video using Xine or mplayer on the same machine, it works
fine.

Only mythffplay causes problems.

Let me know if you would like me to provide more information.

Mark
