I dupe said DVD+R to DVD-R with DVDSHRINK for picky drives.
Use BELARC ADVISOR and see if it will report the make/mode/firmware model of the drive.
In closing, why not make this a warranty issue on the laptop?
I have a VPR Matrix 185A5. The machine will play "commercial" DVDs (movies, etc.). However, it will not play DVD+R media recorded on my home deck.
I have a Compaq laptop which will play these DVDs without a problem. Is there a solution for this? Please advise.
