The only thing holding me back is a DVD writer; I don't have one yet so I couldn't contribute very much.

Although, upon browsing the DVD forum, there are some posts that do a good job of listing media compatability (especially with the Sony DRU-500A). It's just a matter of compiling it into a thread. I may undertake the task if I have some spare time.
One question: How does one check to see if a recorded DVD-R/+R is error free? CD Speed has ScanDisc, but is there a DVD Speed with a similar feature?
