While looking through some old cakeboxes looking for a data disc, I stumbled on a bunch (35+ discs) of old cheap DVD-R media 2x from when I had my Pioneer 102! There was a mix of 3 brands in there. I put one of the Sony (a fake I believe) 2x discs in my 3500 and burned a 2.3gb video file i made. Then I did a quality test in my Benq 1620 and to my surprise I got a quality score of 94! PIE average 12.23 PIF average 0.33. My benq won't even burn this disc.
