Copy and Burn Slow on XP since 9.1.1.0

[Jamin4u]

Version 9 had a copy and burn of 30 minutes.

Since version 9.1.1.0 the one with "Fix: User interface freeze problem in certain cases" , it will copy and burn in 90 minutes.

XP SP3 all up to date.
Drives in Ultra DMA Mode 2.
Settings in DVDfab confirmed.

Update:

When version 9 was released, the first movie I copied the cpu usage was 100%. I changed the setting to use only one core instead of two which dropped the cpu usage to 50%. This did not change the total time to copy a movie. As I stated, a later version caused a slowdown for me.

I just changed the setting to use both cores and the copying speed is back to normal as well as the cpu usage which is 50%.

Whatever changed in the program, I hope it stays.

Thanks for all you do!
