That looks like a transport stream. If so, VirtualDub-MPEG2 won't work with that. Only MPEG-2 program streams are supported.

I'll try, but I don't have much experience with Transport Streams.

The way I understand it, a Program Stream contains multiplexed video and audio for exactly one "program" (like a TV program, or movie). VCDs, SVCDs, and DVDs are all examples which use this kind of stream. But a Transport Stream is designed for multicast, and may contain numerous Program Streams all playing simultaneously. I think this is the kind of stream that satellites, digital cable, and Tivo-like devices work with. Even though it's still MPEG-2 video, the structure of the Transport Stream is completely different.

To support fccHandler
on my picture you can see that four packages are recorded as .ts streams where beside video and audio(s) are also another "useful" data included like teletxt pages with subtitles for the movie.

On audio part of this picture you can see that many audio are recorded as seperate /mp2's. There is also possibility to record all of them as one .ts stream (and demultiplex them later) or we can record all DATA from that transponder again as one .ts stream /see this button .
Whole rec

We can record also as "normal" mpeg2, PVA or even directly to .avi and .mp3

I think Skystar2 Captures MPEG2 Program Streams PS & ES & PVA
So PS Streams should work on vdub ???

Sorry .. Here is the text :
Video/Audio PS (MPEG 2 program stream): This is the standard setting. It produces an MPEG 2 (though not necessarily DVD compatible) compliant file. MPEG, which stands for Moving Picture Experts Group, is the name of a family of standards used for coding audio-visual information (e.g. movies, video, music) in a digital compressed format.

The file extension here is .mpg, or .m2p. Often you can use such a recorded file directly for creating a DVD or (S-)VCD. This kind of recording is also known as multiplexed recording.

Reminder: DVB-MPEG 2 is not the same as DVD-MPEG 2. For DVD-compliance a GOP (group of pictures) must not consist of more than 15 pictures (PAL). But DVB broadcasts often have more than 15 pictures per group. This is not the DVBViewer's fault since the original stream broadcast is saved. But many modern DVD players can cope with DVB-recordings, though.

The site say for recording:

Recording Video in .mpg, .m2p, .pva, .ts

VirtualDub MPEG2 should be able to open the first two.

(DGMPGDec can open all of them.)
