Out of all the great video and audio codecs, there is no way to export to MPEG Layer 1 audio or video. Current versions of Sparkle break under QT 4. So, you can't create and MPEG 1 file from the QT 4.0 authoring environment. Am I doing something wrong? Or, is there no way to do this?

Astarte makes a CD exporter that works with QT4 (I tried it last night). It's shareware.

My experiance with this has been with MP3's. Ya know...good old mpeg 1 layer 3. Quicktime can read a mp3, but if you hit save it will tag it as a Movie file. Although it looks like a movie file (says movie on the icon), and MacAmp can't read it ... it is still a mpeg file.

Sound app still lists it as MPEG 1 Layer 3 if you drop it on a sound app auto typer and open it with sound app.

So it looks like quicktime player 4 still has a few bugs in the mpeg exporting department. However.... the quicktime plugin can "save as source" and tag a file as MPEG if your source file is a MPEG file. So if I want to change any MPEG file's creator to quicktime I run it though the browser plugin.

These problems will proably be addressed in the future. Quicktime's MPEG handling needs a bit more work.

Thanks chibbert for the info.
