Ahh - sorry I didn't read your original post well enough. I'm using ffmpeg. 
The latest CVS/SVN version of ffmpeg is the one you want.

The mpeg is DVD suitable but it still needs processing (I think) to strip out 
the unused data (teletext/subtitle streams). If I am wrong here, someone 
please tell me! If I could reduce the time & work of exporting to DVD further 
I would be very interested.

I am also exporting DVB-T recordings - mostly films. I've been a little 
suprised that most of what I export doesn't even use half the DVD. I'm 
thinking of fitting two films onto each DVD in future - I just need to create 
a script to automate menu creation.
