Thanks again for the good advice.
In the media FAQs which were pointed out, I found the following:
'Your drive uses a database of media ATIP codes to determine what is the best speed for the disc. Updating your firmware is one way to be sure the drive has the latest information about media.'
So how do 'I' know which speed the drive has determined to be the best?
I've just gone and bought a truck load of 80 mins CDRs. Any words of comfort regarding the following?!?!?!...
'Some audio players will not track anything past 74 min, so be sure to limit your recordings to 74 min. Some players will not accept 80min CDR's, even with only 74 min burned on them. So as another last resort, try some 74min (650MB) discs if you can find them.'
Well I don't know why they don't like to make these anymore seeing that people will want to play their CDRs in old audio players!!!
