I upgraded VRD from 629 to 635 and VAP from 096 to 101. I immediately starting getting VRD crashes when VAP tried to run VRD. One crash seems to be immediately after VAP starts processing the file although it usually does process the file after I close the system crash message (although one time the mpg file got left in the QSF directory rather than being transferred to the output folder). The other crash happens VRD goes to run the Ad Scan.
My input files are TiVo and WTV and it happens with both. All I do with VRD is a QSF to convert the file to mpg and run Ad Scan to produce a Drax chapter file.
The VRD change logs so a number of changes effecting the COM interface, and since the COM interface has caused you problems before, it seems like a likely suspect.
When I get a chance, I'll rollback to my previous VRD version and see if the problems go away.
