In my sony dvd writer(DRU 8705), the prblm is that when i write any data frm my HDD into a dual layer dvd, the burn process succesfully completes but after that when i try to run the datas such as games, movies etc. frm that dvd the datas do not run properly( in case of games after half installation process it shows some files are corrupt and in case of movies, the movies do not run at all, here again it shows that some files are corrupt). However, my pc is virus free( i've scanned it several times). I've XP SP 3, 2GB ram. I've nero 7 on my pc. Pls help and also suggest which is the best version of nero to be used in xp. Thanks, Subha.

Are the movies write piracy protected to copy any dvd movies you need a program called any dvd or another one called fab dvd which removes the piracy protection on dvd's

or

click start control panel,administrive tools,computer management,device manager scroll to cd/dvd rom drives right click properties then properties again then tick enable cd digital cd audio for this cd rom device or scroll to dvd regions select the no _ for your specific area
If this does not fix the problem you might try

you might have to physically unplug the leads for this dvdrw then plug them back in this should activate the found new hardware wizard or
you might have to uninstall then reinstall your DVD/CD or uninstall the driver then reinstall for this device
click start control panel admistrive tools,computer management,device manager scroll down cd dvd rom drives right click you will see options to update driver,roll back driver,or
select properties general troubleshoot, select driver click to reinstall drivers click update driver or uninstall then reinstall
