Thanks for your reply.
System 1 is affected by http://bugzilla.kernel.org/show_bug.cgi?id=12309 Also, just noticed that it doesn't appear to have udma capability?! (see attachment).
Regarding system 3, should there not be an error raised or some such? It appears to complete the process, but halfway through the laser is cut?
As for the media, I currently use branded discs (tdk), any recommendations what to shop for?
