fwiw - It uses all 4 Cores and rips through encoding!

If you have an E6600 (Core 2 Dual Core) and a compatible motherboard, you'll enjoy the speed benefits of upgrading in DVD Creator.. The quality is very good too!

The q6600 halved in price a few weeks ago then dropped again in price.. Its a 10 minute upgrade!

I'm finding 4.51 is the best version yet ...
