I purchased DVDfab Platinum a few months ago, and have been backing up a bunch of my children’s movies. I love it!! However, recently the program seems to have slowed way down. It used to take only ~30 minutes to decode and burn a DVD (the wholeprocess from start to finish), the last few times it is taking almost 3 hours… and today it has started to crash my system half-way through the process. Is this my DVD reader, or something with the program? Please help!
Check DMA , drive may have switched to PIO …

Also make sure you don’t have too many running apps/processes…
okay, tried the DMA thing, all of the Primary and Secondary were all selected as “DMA if available” I have no other applications running (well, except Explorer at the moment). It is extremely slow whether I have anything else running or not. When checking the DMA/PIO thing you mentioned above, I noticed that one of my Secondary Channels, showed the transfer rate as PIO, even though “DMA if available” was selected. I am currently backing up a disc, it has already been 1 hour and it is only 40% done. Thanks in advance for the help:)
Then you must follow the advice in the above link & uninstall the seconday IDE channel & reboot.
Alternatively use the script in my signature to reset DMA correctly.
After the burn process please post the log… see link for DMA reset above thanks to Timc
I used the link above to reset DMA… it works great now! Back to how it was originally! Thank you so much for your help! You guys rock! 
Also in DVDFAB Plat. there is a reset dma button also in common settings
