I have a VCD I need to burn (it's an mpg) using something that is compatible with Windows Vista. I tried VCDEasy and Nero but they are saying compatibility issues. Does anyone know of a Vista-compatible program that can simply burn VCD (so that it is watchable in DVD player)?
Thanks.

Nero should work on Vista. Or try a new version. Is it the software? Or is it the file? Sometimes the file is in a incorrect format where it can't be burned to a VCD. You would have to Re-Encode it. Sometimes Nero can do it as well.

Also Not all DVD players can play VCD's / SVCD's / XVID's. You may want to check online if your DVD player supports VCD's and other formats. If not, You would need to convert it to DVD.

The easiest / free program that can do that is "ConvertXtoDVD"

*EDIT*
I know why the person above me has 9% out of 3700 answers. Because he / she is an idiot. ImgBURN if i remember correctly burns "IMG's" (.ISO). Your question is about burning a VCD, or in your case, converting the MPG to burn as a VCD or DVD.

Try ImgBurn. I think that will do what you need.
I use it in Vista to burn CD's and DVD's.
It's freeware and reliable. Check their website.

[Update] TripKore - If you never read how ImgBurn works, and you obviously haven't, then why call someone an idiot?
You are a nasty little person.
Yes, it creates images and then those images are burnt to the disk. It's a two-part operation. I use it several times a week to burn mpg and avi files to DVD's, both as data files and as actual DVD video disks.
