Well, I burnt another disc in my 111L and it scanned fine, TRT fine, looks fine, works fine. So far the pioneer has burnt 4 out of 4 with very similar results. (Hope I don't jinx myself or something!) 6x and 8x on the Pioneer both have quite similar results.
Burning with the 4167B again @ 4x just to see if it goes nuts. Scanning the disk as I write. I'm not going to bother with the H22N as it was unreadable @ 8x and 8x writing strategy begins @4x. So burning @ 4x would make no difference.
Here's the scan of the 4x burn. Amazingly, jitter remains steady and quite low. The PIE here is the only thing worth worrying about. 16x scanning actually makes both the PIE and PIF look better. I'll definitely keep this disc
