I'd like to test as well. I'm a paying client that has changed e-mails and forgot my original account

. (I bet if I'm not too dumb I could figure it out from the email with the registration key?). Anyway, I use to use XP but I am now on Vista. When I have the time, I setup Win7 RC as well. I couple with DVRMStoolbox. The only problems I've had is sometimes Showanalyzer will hang at the end of DVR-MS file, but not always. I'll be glad to test any senarios you think you need testing as I'm not adverse to reinstalling systems.
