I have Memorex 4x and PENGO 4x media. Works good, i have very good DVD backups (Anydvd, Pinacle Instant Copy, the best).
Everything is ok, but NOW i have very big problems burning at 4x!!!
If i burn at 2x or 2.4, no problems (testing using DVd decripter ISO mode and Pinacle Direct Burning).
If i write at 4x... i lost EVERY dvd disk i use.... the burn process is stoped at 93 - 99% with a strange errors....
is my dvd writer damaged? any solution or recomendation please?
