hi. i am new in dvd burning and i had recently bought a Sony DRX 710UL with Nero 6. i had already able to copy dvd movies but when i was trying to copy ISO files and some ordinary files ( 3.0G total ) to a Verbatim DVD-R Nero was able to cache all files successfully but when it started to burn it it stopped at 2% - 3% and it stops/hungs there. i had already wasted 3 blank dvd so i am seeking help, maybe i had setup the configuration wrong or something. the DRX can burn data to CDRs thou. thanks.
