my purpose it to export the files (usually to a roku) so i transcode my 
1080i hdpvr files to 720p using ffmpeg's yadif filter which gives me a 
file without motion problems which i could not get by using handbrake. 
the files play fine in myth video and roku. the cuts usually look pretty 
good and are always time accurate. i compiled my own ffmpeg for this
