Knoppix 7.0.1-EN DVD notes & comments

[Karibu]

Thanks for the inputs...
Cleaning didn't help...
what I kept secret so far is that I used Brasero burner and a
"TDK Rerecordable DVD-RW 4x" which has traces of usage...
I learned that those re-writable DVDs are not always reliable...
I'll burn another DVD+R (read only) and try again...
BTW is there a recommended DVD brand and which burner is preferably used.. ?

@ Karibu
I use Memorex 16x DVD+R (36 cents US each in 50s) and Brasero.
Any dvd recording problems I run into are due to either fingerprints or abrasion,
always obvious after the fact.
