Anybody had this - after 100% encoding a 50 minute WMV from DV AVI, V4 hangs, with an error msg ""The procedure entry point WMCreateBackupRestorer could not be located in the dynamic link library WMVCore.dll" . OK on shorter (1 minute) segments. 80GB spare on data HDD.
Variously, Vegas recovers on 'OK', crashes (closes app), or seizes the whole PC.
V4.0d , XP, Athlon 2600+ 1GB RAM.
