Joesax, someone will come along and give you a more precise answer soon (edit, BFM was quick) but a great site for finding tools for functions like this is videohelp.com/ I find it very handy.
Thanks very much BFM, Amos and Bu Lai En! Virtual Dub doesn’t work with .wmv but tmpgenc did a fine job on its own with no audio sync problems. (The help page that Bu Lai En linked to said that sync problems tend to occur with VBR MP3 and AC3 audio, which I presume are embedded in DivX files or something similar, not .wmv ones).
[quote=“Shenme Niao”]Nero Ultra Edition might do the job.
There’s also another product called NeroVision.[/quote]Thanks. I made the .mpg file with tmpgenc then created the VCD with Nero 5. But after your post I tried dragging the .wmv file directly into the “VCD compilation” window. Nero analysed the file successfully so, as you say, it’s probably possible to burn VCDs from .wmv files in one step using Nero.
