[MPlayer-users] audio leads video

[Geoffrey Leach]

OK, Carl. I'll try again. I'm sure that you will give me guidance if 
needed :-)

My problem. I am recording digital television off-the-air using an HD 
HomeRun tuner, which produces an MPEG2 file. On some of the recordings 
(from particular channels, all the time) when they are replayed using 
mplayer (log attached) the audio leads the video by several seconds. By 
this I mean, a character starts talking before his lips starts moving. 

A temporary correction can be made with seek -1 seek +1

The mplayer command being used is:

player -mc 0.2 -autosync 30 -dr -tskeepbroken -ao alsa::device=hw=0.3 
-vo vdpau -vc ffmpeg2 -alang eng -zoom -fs foo.mp2

The '-mc 0.2' and '-autosync 30' do not appear to have any effect.

'-tskeepbroken' is there because the reception is sometimes poor, 
leading to hard-to-play MPEG2 files.

The problem occurs even when reception is perfect.

The configuration of the system being used for reception and replay is:
  MB: ASUS P5N7A-VM
  CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache 
  Memory: Corsair DDR2-800 2x1 GB
  Disk: WD Scorpio Black 2.5" 250GB 16G cache SATA 3.0
  Ethernet: Realtek RTL8211CL Gigabit Ethernet
  Sound: Realtek ALC1200 (ASUS proprietary implementation)
  OS: Linux Fedora 10 kernel-2.6.27.12-170.2.5.fc10.i686
  Alsa: driver and libs 1.0.20 (local compiled)
  Mplayer: SVN-r29251-4.3.2
