Can any member comment on any of the following media listed here for UK viewers

http://www.bigpockets.co.uk/results.php?main=Blank+DVD&type=category&keyword=DVD-R+Bra...163170c4dc536e
and its suitability for the Pioneer DVR-3100.

I have looked up the machine under DVD Writers but there is no media details underneath.
Any info from an existing user would be most appreciated.

Thanks in advance[/url]
