Some experiences I made recently

Since I got a DVB-T box for christmas I'm trying to capture some TV streams and put them on a
DVD. So I tried out a lot of DVD authoring apps too. 

What should be menitoned as a good app is mandvd (which is available for Debian at least from
debian-multimedia.org). Can help you to do a quick simple DVD.

qdvdauthor is currently in transiton to the 1.0.0 version (Release Candidates are available).
The 0.1.5 binaries for Debian come with xine support only which means that the length of your
MPG clip is predicted wrong (usually 1/3 of the real length). Compiling with mplayer support
solves that problem, but gives some more problems on thumbnail generation and as Jonathan
observed a lot of open mplayer instances. If you want to add several clips and a menu button
"play all" you need the 1.0.0 version at least. I managed to get RC2 working, but RC3 and the
latestst CVS won't work actually on my system. But since there is progress in the project I
think soon we will get those bugs fixed.
