Re: Problem caused by InstantWrite (vobiw.sys)
Click start, run, enter regedit, click Edit, then Find, and enter vobiw.sys and click Find Next.
You have searched for it so you'll get a couple hits on MRU's (most recently used) probably - just press F3 which will keep searching.
IF you hit it anywhere else, write down the data you see.
After regedit reports all done, click OK and then the red x.
