I have used Kaffeine to record a DVB broadcast in the PS format, and
then ran it through Devede to try to author a DVD. The Devede software
crashed, and I followed up this problem with the software author. He
tells me that the problem was not in Devede itself but in DVDAuthor,
which objected to some aspect of the mpeg file format.
It appears there might be a problem with the formatting of the file by
Kaffeine perhaps when using the PS format. I have no trouble using
Kaffeine and Devede together when recording to the TS format.
I have a 4 meg mpeg file produced by Kaffeine in the PS format that I
can send someone if they are interested in following this up.
