Thank you Jeremy and Rafalos.

Unfortunately, I’m running a version of Compressor that calls itself 2.3 When you go into the Extras tab in the encoder section of the Inspector, as you suggest Jeremy, my version has that tick box as well — and it describes itself the same way (Multiplexed MPEG-1 layer 2 audio) — but the fine print says “Select this to create an MPEG-2 Transport stream with multiplexed audio.” When you check it, it does not give you the option of choosing either a transport stream or a program stream. If you continue to keep it as an MPEG-2 in the file format pull-down menu, it automatically makes the extension .m2t And that’s it. I was looking at the Apple site’s description of Compressor 3 that comes standard with Studio2 — it says you have the option of exporting MPEG-2 Elementary, Program, or Transport streams. Time to get work to upgrade, I guess.

Rafalos, a competition in Australia requested the files as muxed MPEG-2 s. Well, actually, they neglected to mention the muxed part, and I thought they were going to be making their own DVDs with the files and delivered .m2v’s and .ac3’s. Then they told me they wanted single files with embedded sound. That’s when I delivered the files as transport streams (.m2t’s), because I saw that my version of compressor made that kind of muxed file, so I assumed that’s what they wanted. Then they said, no, no, this file has the wrong extension. So that’s when I had to “hit the books” and figure out all this stuff about program streams and transport streams. I do not know why they want the files this way. It does seem very archaic to me. I’ve been wondering — is this format more common in Europe/Asia/Australia? Was it a standard many people used to use? Why they don’t want a nice big H.264, I can’t understand.

Again, thanks for everybody’s help.

I kind of skipped those other 2 forums because I find them under attended, as well.

MUXING — right. Unfortunately, the docs. I received said nothing about it. however, it seems fairly evident that that’s what they want. Taking the Transport Stream I exported from Compressor (the .m2t) and opening it in MPEG-Streamclip seems to be the answer — I am able to take the transport stream and “convert to MPEG with MP2 audio”, which creates a single file that has the Quicktime icon, and .mpeg as the extension. That file that is created opens in Quicktime, and the movie Inspector says it’s “MPEG2 Muxed,” even though it’s “kind” (in the preview column of the finder) decribes it as an “MPEG-1 Movie.”

Thanks for your help. Hope this might help others.
