TIA for any assistance, the folks at Nero are not responding to my tech support questions and I'm getting tired of waiting.

My issue: I use Nero to burn DVD's. I have a Sony DRU 830A burner, and am using Nero 7 enhanced. I have used this same combo for a few years, but just replace the burner last week as the previous one needed to be retired. I burn .vob files to dvd -R discs and have had no issues till the new burner was installed. Now, when I burn these files, the completed DVD will not play in the rom drive of my computer and is being identified as RAW format. But the same dvd WILL play in a stand alone dvd player just fine. The disc is finalized, but will not play in my computer. I have lastest firmware installed for the Sony burner.

Can someone help me figure out what setting I need to change to make these otherwise playable dvd's work on my computer?
