Need Help with New GSA-H22N

While not totally new to DVD burning, I’ve only done enough to “get by”. I am a photographer and burn DVD’s of my photos for clients.
Just purchased a new GSA-H22N and using both ImgBurn and Nero Express, I find I am unable to burn a usable DVD.
I’m using MCC-004 Verbatim discs and converting DVD+R to DVD-ROM.
Any ideas?
I’d really appreciate getting this drive running - I’ve got client discs I need to get out.
I get a similar error from Nero - seems to burn OK, but the fails to verify.
Here’s the rest of the info from ImgBurn

Try burning at lower speeds. If this doesn’t work, post more about your hardware and os config for more input.

make sure you’re using a 80 wire ide cable with your drive.

are you burning just jpeg files to dvd disc or are you burning a iso image of a slideshow that you created with Photodex Proshow DVD which is a slideshow program??
