Quality scans are fairly reliable indicators of burn quality, so just b/c a CD/DVD is still readable doesn't mean the scan is worthless; it just means your standalone player is pretty good and not too 'picky' on the quality of the media.
Just because some G05s have 'held up' does not mean one burner is superior or better at burning them than another. The degradation is a media issue (dye formulation or something else), not a burner issue. The fact so many users have problems with basically any Ritek DVD (Ritek R03, G04s, G05s specifically that I've seen and read posts on) means it's the way Ritek manufactures them and a near complete lack of QC. Add to that the fact I've not seen a single thing "Ritek," whether CD-R or anything DVD with any kind of warranty. No warranty of even a lousy year tells you they can't be trusted for reliability. Since Ritek offers no warranty, there's no reason for them to ensure their quality, so they'll continue just pouring them out, with no regard for QC/QA. I've burned those sorry things on a Pioneer DVR-108, BenQ1640 and Plextor 716a with the same lousy results and later degradation. No firmware, burner, write speed nor write strategy can turn Ritek crap into a 'long-lasting example' that will store your data for years.
As for Ritek degradation, I've got plenty scans also where PIE/PIF error totals were 2x-7x the original scans in as little as 2 WEEKS!!! Anyone who wants peace of mind will avoid anything Ritek... :iagree:
