I record ATSC (US HD) OTA using an HD HomeRun tuner. I've had serious A-V sync problems (dropped frames, large values of AV_delay) on replay of the MPEG-2 recordings. There's a patch for mplayer on the nVidia forum - http:// www.nvnews.net/vbulletin/showpost.php?p=2092901&postcount=1195 After applying it to the 29 Sept source, I've had no more problems. Is this patch being considered for inclusion in the official source? FWIW, here's my info.
