I know it is not 'supported' or says so in the FAQ, but I have TV capture issues that I hope someone might be able to help me solve....I successfully capture, but it is too damned fast and I have to PLAY the captured file at --speed .65, here is what I am using to capture with a Wintv Card and SB live:


mencoder -tv on:driver=v4l:norm=ntsc:device                                                             =/dev/video0:adevice=/dev/dsp2:width=320:height=240:chanlist=us-cable:channel=2:                                                                                 audiorate=48000 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1000:vme=5 -oac copy -ofps 25

Note thta for some reason it ignores my codec choice too, and captures Un compresed, however this is all a learning experience and I am further now than ever before.

Now to play this file I still have to set the "-speed .65" option ( shomewhere around >65 to .75 makes it right).

Any ideas? did I miss somthing in the tome-ish documentation on speed and codec calling?? can someone pint me to the right docs to RTFM?
