Im using the usb cable that came with the burner.. im assuming a 2.0 cable.. i didnt get any buffer underruns with the burn and the burn came out ok. just 2 hours 45 minutes later... im not too sure what the booktype setting is with omnipatcher.. but there is an option in the program to have it optimize settings automatically for optimal drive function and I clicked that... I have read some stuff about needing motherboard updates, but the computer is only 2 years old and I dont see it having too much incompatibility with newer burners.. the one thing that is uniform is that all software programs I have tried are all seeing the same read/write rate of 0.6x/.7x
I'd try to defrag the hard drive, maybe even twice if it's really bad. Then uninstall the USB controller and reboot. Do you have any other USB cables you could use? There are instances where you might have a bad cable. Also check for spyware, adware and viruses.
Mort, I finally got a chance to test out the auto-booktype and it worked, at least on a +RW disc. Thanks again for all your help with my burner.
Sure thing squizzle. It should work on dvd+r's too then. Thanks for the help with setting up batch processing.
