Hi!

That might be due to a buggy transport stream. Did you use dvbcut 0.5.0 or 0.5.1? The older release lets some incorrect TS packets pass through. dvbcut 0.5.1 didn't crash yet on my system.

- Aspect ratio was wrong in mplayer. I am not sure if this is maybe an mplayer 
problem.
- I have a topfield TF-5000PVR where the ts-streams have the extension .rec.
This extension should also be in the 'open file' dialog.

Ah well. Please add .ts and .mpeg, too. :)

- When saving dvpcut-files and program streams the program should by default 
propose
'foo.dvbcut' and 'foo.mpg' when the original file was named 'foo.rec'
- Sometimes (very seldom) I have movies from dvb that are to large for a dvd5.
In this case I use 'tcrequant' from transcode to reduce the size of the mpeg2
video (.mpv) after demuxing and cutting in projectx. After that I would
multiplex the result with mplex (mjpegtools). How can I do the same with dvbcut?
Do I need to produce a complete mpg (audio and video) with dvbcut, then demux
it, tcrequant the video, and then multiplex again?

That's the generic way unless you have a requantizer that works on transport or program streams. By the way: Transport streams from dvbcut have broken PCR timestamps (due to a bug in ffmpeg). Mplayer and xine play them fine, but better use PS format if you are going to postprocess the output.

Maybe it would be good to
have an option in dvbcut to output video and audio in separate files without
multiplexing them, to directly requant the video.

In which format? PS, TS, PES or raw?

- In my normal procedure to go from a ts-stream (.rec from topfield pvr) to a
dvd I use mplex to multiplex audio and video. From the mplex manpage:

FUNCTION LETTERS
       -f|--format format_code
              This command allows one of a number of convenient preset  output
                ......
                8  -  DVD  (with  NAV sectors). Don't get too excited.  This is
                really a very minimal mux format.  It includes  empty  versions 
 of  the
                peculiar VOBU  start  sectors DVD VOB's include.  This is 
enough to
persuade some hardware players to play the stream but is a long way from full DVD authoring.
                9 - DVD.  As above but without the empty VOBU sectors.

As I use dvdauthor afterwards I use the format '8' (I think dvdauthor would not
work with '7', but I am not sure). What kind of format does dvbcut use? Will it
work with dvdauthor?

The PS format is pretty similar at least. Program streams from dvbcut start with a pack and system header, padded to 2K, followed by single PES packets, each with its own pack header (and a total size of 2048 as well). I'm not sure whether all bits inside the a/v streams are DVD compliant, though.
