I tried to tackle this problem and it became overwhelming.
My burnt DVD's were corrupted with artifacts and playback would stutter on the drive that burnt them.
Elby Clone DVD2
Morpheus Nvidia Burning driver pack
The MS drivers would make a burn fail with Sonic.
I needed to add a Vantec (NEC) usb pci card to avoid my onboard USB; cheap from newegg.
Upgraded to 811 w/ HSOQ!!!!!!
Using Ritek DVD+R media I now have succesful burns. I tried an experiment: I wanted to test the booktype sertting since I kept forgetting to. at work we have an older DVD recorder that would not play my DVD+R burns. So I tried using the booktype, but I also wanted to see what would result from burning with all services and extras running. I have a lot. Kaspersky Realtime Virus protection, Windowblinds, Acronis True Image monitor, Cursor XP, Diskeeper service, and many many many more. I use 250 mb of mem standard.
My burns came out flawless. I still have the onboard lan chip enabled but as I said earlier I use a pci USB card; which probably made the biggest overall difference besides the upgrade to 811 w/ HSOQ.
Don't give up!!!!!!!!!!!!!!!!!!!!!!!
