OK in a nut shell... Mum buys DVD+RW disc and records something onto it. If only she writes to it she has no problem. If I use my DVD Recorder to blank the disc or even Nero (full or quick) mother's 5045 now refuses to even acknowledge a disc in the unit saying "No disc present" or something similar. Would a firmware update fix this or is this something else? I have been involved in another topic where we're extremely close to replacing the DVD drive with another drive. Mother is very anxious about firmware updates after we killed her Apple Mac. Luckily it was Apple who told us to update it and they replaced it.
