RE scan size, I tried cropping and attaching but it insisted it was too big even in JPEG format so I gave up and just image linked it instead. I see looking at the 'how to post' link that PNG is the preferred format so I'll do that that in the future (sorry ).
OK, OK - a few months ago I had a problem and it got solved: http://club.cdfreaks.com/showthread.php?p=1659942#post1659942
So I thought I'd check the temp and it was running pretty high at up to 60c.
So I did the same thing, burned a disc and it got a quality score of 90, which ain't bad. So I guess that was the problem. After cleaning out the heatsink again, temp dropped to 35c when loaded.
However it has crept up to the 48c/49c mark whilst loaded now but the heatsink appears clear so I am a bit concerned...
