I've only burned 2 discs so far (Acro Circle 16x DVD+R @16x and Philips 8x DVD+RDL at 4x) and so far I've been quite impressed. I didn't think any drive could beat the Pioneer DVR-111D's performance on Acro Circle 16x DVD+Rs... but the LG H22L is showing results on 16x burns that look comparable to the Pioneer's 8x burns on the same media type! The jitter looks quite nice at only 9.9% (according to my DW1640), which is quite low for a 16x burn.
If this is how it performs with only mid level quality media, I can't wait to see how it handles some really good stuff (like my Maxell BQ 8x DVD-Rs!!).
Don't worry, I'll post scans and do lot's more testing still
EDIT: The Philips 8x DVD+RDL burned at 4x looked half decent too. 4x was the max speed it could burn it at, and from what I saw of the scan before I left for work, it looked decent.
