I was having problems getting Nero to burn an 842 mg mpg file as a VCD (or a data file) to a 700 mg CD-R, so I read about MVCD's. I downloaded an enahancement from http://www.molevcd.de/ for TMPGenc and was able to shrink the file to 593 mg and it plays beautifully. In addition, I created chapters using VCDeasy that I wouldn't have been able to do with Nero.
Has anyone played around with MVCD? I understand that you can shrink an entire DVD to an SVCD format with it. The better players like the Philips 642/37 supposedly can handle it.
