When I try to render a wmv9 clip my computer reboots itself. Is there a patch for this or chould I have something else installed that I do not know about. Should I reinstall Vegas? Help me out with this one.
Try WMEncoder in case your installed library breaks what Vegas is expecting. You can frameserve with Satish's plug or convert from DV/uncompressed/MJPEG as an intermediate codec step etc.
If microsoft WMEnc bolts on you, you might have some icky memory (and almost every hardware component etc), which a number of free web tools might help you determine if a BIOS check "apparently" finds nothing.
1. Hyperthreading enabled or possible?
2. DirectX9b installed?
3. Any similar problems with MPEG-2 encoding, or non-DV codec media (generated in Vegas or outside using uncompressed etc)?
4. Always at the same point (if you are watching or recording the PC screen externally)?
