Turns out - and if this isn't news, i.e., it's been posted about - sorry - can't find it.

With both installed and DVD43 active, you get a bad_pool_error BSOD at the end of an Itunes burn.

This was driving me crazy, and for days I was trying to figure this out untill I stumbled upon a post on dslreports of all places. If you close DVD43, no problem.

Think there's a fix? Why would this happen. There might be problems with anydvd and some others as well, but I haven't tried.
