Hauppauge streams can be used directly when you want to convert to other formats.
However, if you want to create a dvd with dvdauthor you might get the following errors:
DVDAuthor::dvdauthor, version 0.7.2.

To fix this you need to demux and mux (remultiplex) the file.
This will add the needed NAV packets in the file
sudo zypper in mjpegtools ProjectX
projectx.sh -demux original.mpg -name fixed
mplex -f 8 -o fixed.mpg fixed.m2v fixed.mp2
This will create a fixed.mpg file that you now can use with all tools
