Finalizing disc error

[DeafeningSilence]

At the end or near the end rather, the disc is suppose to finalize, but it does not, I can hear my drive struggling, why? No idea, thats why Im here. This has never happened before, and have already ruined 3 discs and have downloaded 2 separate ISO's to see what was wrong, I noticed the ISO's were somewhat similar, the file size was exact, I dont know what changed had been made, but Im not 100% sure its the ISO's doing. The finalizing process usually takes 20 seconds, and can use up to 3 attempts before giving the error message saying something like "Error finalization misread", not too sure the exact message. Any ideas what the problem is? I'm using Memorex DVD R + DL, and they have worked for plenty of other burns.

A log is nice.

The only logs were dated as December of 09, which is obviously incorrect, but it shows as the latest logs in my list.

And I dont think those are it. Firstly the file size is wrong, and the duration was only 30 seconds. I couldnt find any other logs that were from my previous burns.
