In answer to my original question....Imation 8X dvd+R work fine on the 5005.
Â£9.99 for 25 +Â£2.50 postage,P.C.WORLD online (cheaper than Argos).
Other offers i've seen are;
Maxell (-r) 25 for Â£9:99 inc postage:www.play.com
MEMOREX (-R) 25 FOR Â£8:99 MORRISONS(Supermarket).I wouldn't know if they're good media for the 5005.
I know you can get Datawrite and ritek etc.cheaper but the 5005 has a reputation for being a bit choosey!
