Just wanted to post a resolution to a problem I was having with Cubase 6. Everytime I closed either the 32 or 64 bit versions I would get a video engine stopped working error. Thanks to Chris and Jeff at Yamaha support the problem was resolved. It was as simple as updating Quick Time.
As a side note I was also getting an error on my Cubase 5 32Bit program as well and it cleared that up.
Hope this helps anyone else expierencing the same problem!
