I was able to get ISO burning working just fine in Windows 7, but I'm having trouble with burning regular files (using the built-in Explorer burning functionality). In Vista, I think I selected the files I wanted to burn and just clicked Burn in the toolbar.
However, when I click Burn in Windows 7, it ejects my tray with a "please insert a writeable DVD" message even though I have a blank CDR in there already. Do I need to format it firsT? Vista would detect and offer to format it as part of the process. I don't want a rewritable or open filesystem disc, I'm just trying to burn some .mp3s to CD to play in my car.
