Thank you very much, Bernhard,
You seem have the good ideas. I will try to
absorb and try the options. One thing Im facing is
that, the concatenated MPEG file has to be able to
play back from both PC and recorded to DVD. To have
several files on the DVD is fine, but how can I have
the MPEG files playback together?
Maybe I can look into dvdauthor to see what they
did to make the separate files recorded to DVD while
can playback as a whole.
The reason I first chose cat is because it doesnt
require double the disk space.
Cat tempfile >> finalfile, instead of cat tempfile1
tempfile2 > finalfile.
Just briefly looked at mpegtx, it seems to require
double the space to concatenate the files. I would
like to be able to just put all the files together
using just a small sized temporary file, without using
a totally separate file. Is it possible with mpegtx
like what I did with cat >>?
Thanks again for all your help, Cindy
