Problem with finalising burns

i have a problem with nero burning avi files it will get to finishing stage where it says finishing and like 10 seconds to go and it never finishes i let it go for over a hour to be sure it happens about 3 to 4 out of every disc any ideas?

If a disc can’t be finished or finalised then it could be due to poor media quality. What brand of disc are you using?

im using memorox

Please download CD-DVD Speed, run it, put in a blank disc, and post the information that appears in the ‘Disc Info’ tab. This will give us the Media ID of these Memorex discs…
