Hello Everyone
I am running Windows XP SP 3 on my viao VGNt-250
I recently started to have issues with my cd/dvd burned Model matshita uj-822da I am able to able to read and write cds but for the DVDs anything I burnt in the past I am not able to read anymore however I can read pre-recorded dvds. Also if I insert a blank dvd, it doesnt recognise the media I telephoned Sony and they advised me that maybe the drive needs to be replaced. Personally I think they are wrong. All my dvds I previous backed up can be read on other computer but not on this laptop. The only thing I have installed before any of this started was ITUNES 8
The DVD burner programs I use are ROXIO and NERO.

Any suggestions will be greatly appreciated.

Something when you download itunes messes up the driver. You gotta fix it through the registry somehow, My roommate told me that's what happened to hers and I told her about mine and mine happened after itunes too. She went to bed before she told me how to fix it though. You can find it on the internet she said. Itunes and that cd/dvd rw don't mix apparantly. pisses me off

You need a new drive. Pre-recorded DVDs use a different recording method than recordable DVDs. They use pits in the plastic that is produced in a press. Recordable DVDs use a laser to burn a colored dot into a dye layer in the plastic. It's possible that a failing DVD drive can read one and not the other.
