ummm...you do know this is a mac forum, right? well, guess i'll be the first to say it: get a new mac, and you won't have the problem with the DV7, because you won't need it!
okay, now for the real help. have you tried asking at the
pinnacle DV7 forum ? there might be someone there who's got the same problems as you.
as for other products, i know that dazzle has one,
DV editor/SE.
don't know any other pc products. used to do a lot of capturing/editing on pc, but this was before the invention of DV. used a pinnacle DC something, don't remember. don't care, it was a pain in the ass; it's pretty sad that after rendering each project, i had to shut down the computer for a good 10 minutes, because the thing would freeze.
macs and dv are a godsend...
