I bought Pinnacle Studio 8 at Fry's when it went on sale for $50 with a $50 mail in rebate. For free I figured what the heck. Works great on my system. The Studio 7 demo wouldn't work though when I tried it last year.

I'm running
Win XP Pro
1.5 P4
120Gb WD 8MB buffer
1Gb RAMbus
AIW Radeon 8500DV 128Mb
Capturing through IEEE-1394 from a Sony miniDV

Editing is easy enough and looks fine for me.
