3305/05 errors when recording to DVD-R


I recently purchased a 3305/ 05 and returned it to the store 25 mins after purchase as it wouldnt play pre recorded DVD’s. I brought home a replacement, and while all seems fine with recoeding on +rw, when I try recording to -r, after I press the stop button,the display says it is updating then states that the recording failed to stop. when I reinsert the dvd-r into the drive it says it is blank. What could be the problem?

Any help would be great!

Also is the firmware upgrade a good idea??

Thanks. :slight_smile:
