Thanks Joe I will try that. I tried a few things last night after I posted. I was able to render all the subclips to AVI with no problem and then I rendered to mpeg-2 with no problem. This adds another step to the process but it works. I am using version Pro 8.0c with 4 gig of ram. I actually loaded an older version 5.0 in a VM on the same desktop. I tried the same render and it worked fine rendering right to mpeg-2 so I think it’s related to version 8.0c
