Can anyone reccommend the best dvd’s for the Sony DRU510A + RW? Or are there any makes that DON’T work with it? I’m in the UK by the way.
Currently, I am using 
Verbatim 4X +R (Reorder #94589, Commande No. 94589), and it had yet to give me a coster. 
Today I will go and pick up a 5 pack of the newly released 4X +RW from TDK so wish me luck

The Verbatim and TDK 4x +R media I’ve been buying all come from the same factory (media code is RICOHJPNR01), and they all work great in my Sony 500AX. The Verbatim 2.4X I was using previously also appears to be from the same factory.
I personally prefer the TDK because they have a nicer coating on the label side (and more space to write on).
Here is an list over the media that is supported for this drive.
