Re: [opensuse] openSUSE 11.2 download does not install


First of all, thank you everyone for your helpful input.

The disks that I was having trouble with were RiDATA DVD-R.
When selecting the Speed to 1.0x and the write mode to DAO explicitly I was
able to burn one DVD. However, K3B would report that it was going to use
write speed of 2.0x. See below for mediainfo data.

I had also tried a Fuji Film disk on all Auto settings and it worked perfectly
the firts time.

Thanks to all.

Quality of DVD blanks does not generally correlate well to brand names.
Generics can be top quality, and brands you might think you could trust
often fall short. Read
before you buy any more. Any time you experience failures with what you
bought, switch to slower speed burning until you run out and can get
something better.

Absolutely, I always check that page. Another one is:

My last purchase was DVD-R by JVC, a brand I'd never bought previously.
I'm about 60% through the spool of 100 with 0 failures so far. Others
with very low failure rates were Maxell and Taiyo Yuden. High failure
rates have come from Sony, Philips, HP, Memorex, Staples & Office Depot.
Last year I was using about 200-300 per month. Now I'm down to probably
less than 40/month.

I currently use Verbatim dvd+r, which is listed in the above link as "1st
class". Absolutely no problems, since some years.

You have to check the code with dvd+rw-mediainfo:
