Pinnacle has recently released v10 of their suite, and many places are offering v9 for free (after rebate) to get rid of it. I've used v9 for a couple of years and for the price (under $100 when released) it's a perfectly acceptable suite, a significant upgrade from v8.

You mentioned Hi8 tapes so be aware that you're talking about an analog input from your camcorder to your computer - you'll need some type of hardware device to connect the two - unlike a digital camcorder which only requires a firewire card in the computer and the software.
