Pardon me, but I know what I'm doing.  My  script derives from one of my 
most intense empiric learning experiences under punitive pressure ;-)

I know cute soundcars use 'Capture', but not the mighty Audigy2 ZS:

$ amixer -q sset Capture 100%  unmute cap
amixer: Unable to find simple control 'Capture',0

As I wrote, the mixing is rater fancy...

Equally bizarre with the Line control: there is only Line Play, and not 
Line Capture.  If I mute Line, I can't record it.  In Windoze (CLSB 
Mixer) there's no Line Capture either, only Analog Mix...

More info:

Also, for the curious, I include my complete control list at the end of 
the message.

>>3. Is there a way to make mencoder split the files at certain
Owwwww.  Well, I'll have to emulate that: "-endpos $SIZE" with a loop 
monitoring the current file size, and starting a new mencoder a 
milisecond before the current reachs $SIZE... I smell further desynch... 
¿or less?

I can't understand why the audio in line-in can get out of synch with 
the video, sounds like quantum mechanics: ok, the sound and the video 
capture cards don't always agree on timings, but that doesn't means that 
after an hour of recording the audio is being transmited 20 secs. ahead 
of video... supose its a problem with the encoder, which should resynch 
(reset timings?) every now and then... so starting a new mencoder 
process every 10 mins should provide better results, and some more hassle.

Yep, it's menus what I need.  There's GNU VCDImager/VCDRip__, looks 
good, but I would need to write the XML (ugh!) by hand (agh!), as it 
seems there's no GUI.  There must be at leat one authoring GUI, I 
expect... anyone?

Thanks again.
