Pioneer A07 problems

[Grumpy]

@simonwood
Firstly, I have the same Pioneer burner!

I've noticed on the dvd's I've backed up recently that towards the end the dvd will freeze up.

I presume you are talking about movies you have backed up? And I also presume you are having this problem when playing those backed up movies?
Do you have labels on these backed up movies? If so it is more than likely caused because of the label. Ive seen this happen before with labels on blank DVD's!

Do you think it's wearing out

It's possible but not likely!

I have the latest firmware on it

I am not aware what is currently the latest but I use 'Nils' 1.16 Firmware Hack!

I used Nero, DVD Shrink and DVDDecrypter for my burning software.

I use CloneDVD2 and AnyDVD. I only read the DVD's with these 2 programs, but I use Nero to write the DVD as well.
If you dont have labels stuck onto your DVD's then may I suggest you try CloneDVD2 and AnyDVD. There are trial versions of these programs available. Then if they work for you, you can purchase them once the trial period expires. 'Tyler Durden' had posted a tutorial on how to use CloneDVD2 and AnyDVD together. You will find that tutorial here.
Hope this helps solve your problem!
