[H-GEN] dvds

[staeci at yahoo.com]

I got a friends panasonic dvd drive to work by swapping my cdrom for it no probs.

downloaded the software and kernel patch (2.2.13) from http://www.opendvd.org/linuxdvd.html

but when actually running the command to play it said it was unable to find the first packet.
I think it was mpeg2player which was saying this.  As far as I can tell it cats the .vob file
to the DeCSS software for decoding and then pipes it to mpeg2player.  I'm thinking that it
was just treating the dvd as a normal cd and so couldn't read the extra layers of the DVD.


on a different note does anyone recall what the argument for vi/m is that sets the number
of columns of each line?

I would like to electrocute everyone who uses the word 'fair' in connection
with income tax policies.
