Error Code )x80020063 & Burn iDVD

Question

Have been trying to burn iPhoto files to DVD-R 4.7 GB discs (Verbatim). They seem to work OK but after disc is ejected from drive and the verfy==ify is complete, I get message "This disc did not verify correctly.... Because disc is unreliable, discard and try again. Error code displayed.
Using disc afterward, it seems to be OK. but this continues to happen on each new disc.

I'm having this problem with CD-Rs on my new iMac. So far 3 good burns from the Finder against 5 bad. The first 4 failures died with 0x8002006E and the most recent with "Burning the disc failed because communication to the disc drive failed. (Error code 0x80020022)". Visually all the burns failed with about the same amount of the diskwritten. The DiscRecording.log visible in the Console app shows the writes failing at the same spot (except for the first which is a nonsense number):
+Finder: Write (10), block: 4294967146, count: 32 -> 3/0C/00 Medium Error, Write error+
+Finder: Write (10), block: 94240, count: 32 -> 3/0C/00 Medium Error, Write error+
+Finder: Write (10), block: 94080, count: 32 -> 3/0C/00 Medium Error, Write error+
+Finder: Write (10), block: 94144, count: 32 -> 3/0C/00 Medium Error, Write error+
The last failure showed this:
+Finder: Burn sense: 4/09/01 Hardware Error, Tracking servo failure+
+Finder: Burn error: 0x80020022 The device failed to respond properly, unable to recover or retry.+
Which is beginning to look like a hardware or firmware failure (some other forums seem to suggesting that the problem started with a firmware upgrade). I'll be checking with Apple support directly.
One other oddity, I've tried selecting 8x burn speed - the default is 24x - but DiscRecording.log records this in every case:
+Finder: Requested burn speed was max, actual burn speed is 24x.+
For the record I'm not using a particularly reputable brand of media (Infiniti's from www.medea.co.uk, bought locally) because I thought I'd start with the cheap ones and work up. Messages in this forum and others suggest that the 0x8002006e problem occurs with all brands of media so I'm not confident that upgrading would fix the problem.
