I've had some problems with the render to disk issue. One fault is that if you are using win98 second edition there is a problem with mapped drives. There's a patch posted at Microsoft. I forgot the name of the file, but if you scroll down the list of patches you will see it. Just look for a file that mentions "mapped drives". Also, if you installed a graphics program AFTER you installed Vue it may have overwritten a Vue file. I know it sounds weird. But that is the only explanation I could come up with. If the Microsoft patch doesn't cure it, re-install Vue. Good luck.
