My Targa 1600 laptop has stopped playing dvd movies on Power DVD software that was preinstalled, it just hangs. I have tried the uninstall and reinstalling the software but without success. Dvd drive will allow read / write data files from cds. Any ideas or is it time to dump the dvd drive and install new hardware. Does anyone know if the dvd drive on Targa 1600 laptops is built-in and can not be replaced without having an external drive?
