Here is what I did for a quickfix...
Burn all your stuff with UDF instead of ISO standard. In nero when U select the type of disc (data audio etc) in the list, almost at the end there is "Data - UDF" or something like that.
That's about it! Worked for me!
PS: In my case even the Windows write cd tool did not work. Have no clue about the problem. Came out of nowhere and hit me like a brick.
Hope it helps!
