I bought a set of 10 DVD-R media produced by Sky Media (website here, seemly not working) and I had a bad, bad surprise. In fact, none of them worked. Burning was fine, then every last one of the discs had unrecoverable erors starting at 30% to 70-80% (while reading the entire disc). The DVD-R discs have been written @ 2X (first two of them). The rest i’ve burned @ 1X and still the unreadable data was there. Impossible to use, a total crap. I’ve tried to access their website and ended up with DNS errors :a Seemly, they produce probably the worst DVD-R media ever. The CDs they make are ok, though. But I was about to lose some good money if I had deleted the data from the HDD right after burning each DVD-R.
If you have any knowledge of those DVD-Rs please reply.
