Yep, already tried that, but it doesn't like DVB source mpg's. It takes PS files, whereas DVB sources appear to be "elementary sources", as identified by Manzanita's MPEGID program.
I have spent 12 hours searching google-- to no avail. I am assuming (hoping) that this is so esoteric, developers might know of this but it won't be out for mass consumption.
I think this will be important as there is a growing community of FTA DVB satellite HiDef enthusiasts. Thus I'm looking for an easy way to archive.
