[MEncoder-users] strange with mencoder

[Igor]

Hi

I have the card Gotview PCI DVD Deluxe with mpeg2 encoder.
But, if I will try to VHS-capture with option -pvr abitrate=128 (only with 128!!!) I will have the
mencoder's error (with abitrate=128 - is OK)

$ mencoder -profile capture pvr:// -o ww.mpeg -oac copy -ovc copy -of mpeg

I don't understand which figure I should write in -pvr vbitrate=xxx:vpeak=xxxx
If I will write vbitrate=6:vpeak=7  I will receive the file with very slow videobitrate
Also I don't understand why I have really audiobitrate 384.0 kbit/25.00% , if I wrote
pvr=abitrate=129 (129 kbit/s)

Hereafter you can see my settings and my results
