I also don't want to keep paying $23 a month for software that is not 100%.
Software as complex as Premiere Pro will never be 100% bug free.
I'm also inclined to believe this is more of a system issue than a PP issue. I don't recall other reports of this nature, and it works fine on my own system.
The only other thing I can think of to suggest is another FireWire port, possibly by adding a FireWire card to the system. I've read that the chip makes a difference, so research over in the Hardware forum.
