If you wish to xfer the ts files on yr dreambox to PC or Mac, then I thoroughly recommend
MPEG Streamclip
Just go to
http://www.squared5.com/
and d'load for your OS.
This s/w will open most video formats and convert to most video formats, incl H.264.
It has a built in ability to call up your dreambox (store yr LAN number) and then from the list of movies on yr dreambox hard drive, you select the one you want. It shows or plays in a window and you can edit out the bits you dont want and also remove the unwanted foreign audio tracks. You then export to whatever format you want and save to your computer hard drive.
It ships the file over, converts if necessary and writes the new version.
If you open a group of (say) mpegs on your PC, it will lay them out in sequence in the window and you can save as one movie.
It is the best bit of free mpeg software Ive come across and surprisingly not better known. PVAstrumento is no longer supported but it is also good. I use MPEG Streamclip for all sorts of video editing and re-formatting.
