vcd/ video dvd howto

[Na Zo <perl-w@freemail.hu>]

Hi!

Could anybody tell me where can i find any information about
how to write (copy) a video dvd or cd? I need dvd, but maybe
some are interested in cd, maybe the same way.

I' ve tried to make an iso with 
dd if=/dev/sr0 of=isofile
, but it made to me always a too large isofile. (about 6- 7
GB, i don' t remember exactly, but it is too large for a dvd
- i think.) If i' d get the correct isofile, maybe i could
make an udf fs isofile, and write it on the dvd, but not sure.

If anybody would tell the all process (or could give me some
URL, which will tell it to me), i' d be happy.

I' d be rather interested with "a command line way", so
maybe i could do it with k3b or xcdroast, but a command line
way would be much better.

Thanks for the answers.

Csaba.
