I’ve been trying a few different media in my new Sony DRU-800A (with f/w KY04). Some have been not so good (RicohJPNR02, RicohJPNR03, CMC MAG. AM3) while others have been “good” (well under the max 280 PI, max 4 PIF)

But, how to choose among the “good” media?

All 4 were scanned with KProbe 2.4.2 at 4x, ECC 8/1. So:

[ul]

[li]Is it better to have just 6800 total PI but 300 total PIF, or (higher) 120,000 total PI but (lower) just 110 total PIF?

[/li][li]Or, is there any real difference between total PIF of 100 or 200 or 300, or is this just noise once it gets this low?

[/li][/ul]

One final newbie question: If PIF are “uncorrected” PI errors, why do they not result in data corruption on a data DVD? What corrects the uncorrectable errors?
