Would be fine if mplayer can use some of that code. I put a jpg
(vStrip-Screenshot-recognized-delay.jpg) on incoming there
vstrip report these thingie (ran it without a matching .ifo file was there so
it seems to be in the .vob) Too the .ifo-Parsing is a nice thing. You will be
able to see the language of the ac3 stream. The DVD I used is disneys
atlantis. I ran vstrip over winex , maybe someone get it to compile under
