OT: mpg1 issue

Client wants disc for product announcement. Did several of these already, so I just did the same thing as always. Rendered the video to default mpg1 in Vegas10e (Can't remember for sure, that is the lastest, yes?), and burned to CD with ImgBurn. The discs played fine in my W7 laptop with Windows Media Player. Gave them to the producer. Played fine on his Mac laptop with QT. Gave them to client, it either doesn't work at all (WMP says something about an error it can't figure out), or it does play but is extremely grainy. The producer dropped it into an XP desktop and it told him unknown file error. I haven't a clue. Did this the same way I've done the last 20 or so for them, and never had a problem before. Anyone else run into something like this?

Not sure why it worked before and not now .. but ..

mpg1 is VCD. You say you used ImgBurn. I'm not familiar with that program. Did you create a VCD or did you just drop the mpg1 file onto the CD?

A VCD compatible mpg1 file on a CD is *not* a VCD. A VCD has special file structures and extra folders. For instance if you have a valid VCD and copied all the files and folders over to your hard drive, then put in a blank CD and burned them from the HD .. you would not have a VCD, but a CD with files and folders. If you put that disk into a DVD player (or software player on a computer) it would not be recognized as a VCD. SOME players may be smart enough to figure out how to play the mpg1 file itself .. but it won't be as a VCD.

Interesting. I don't think I've ever gone VCD with this client. It was never meant to play in a DVD player, just as a file on a data CD. Thanks for the pointer. Perhaps I'll give the VCD angle a try.
