Hi to all.
I’ve a ugly alwful 811 (could I wait to buy it 1 year ago?)
the media I’ve always used were Memorex DVD-R 4X, always perfect.
Now I can’t find them more, I can find only Memorex DVD-R 8X.
The fact is that I’ve found a good offer on ebay, I must buy 100 DVD.
Does somebody know if they perform like 4X? can I write them at 4X with no problem??? or I have to use that tool I’ve seen (omnipatcher or so)?
all info are welcome. 
thank u!
The 811S firmwares are very outdated in terms of firmware. They do not support most of the 8x -R media codes on the market, and thus will try to burn them with a generic write strat (translation: bad results). You will most likely get very poor results with 8x -R on this drive.
just a curiousity:
and if with omnipatcher I say that that DVD 8X code must be burned like a Memorex 4X what happends? still same results like 4X or nothing change?
You can do that. And you may get good results. But OP can’t do it; you’ll have to manually do it with a hex editor. OP can work only with media codes recognized by the firmware. The problem is that the 811S can’t recognize most 8x -R codes, which is why the burn quality is bad because failure to recognize means that the drive will use a generic strategy. So the only way around this is to manually edit the firmware so that the drive can recognize 8x -R codes and then use OP to switch the strategy to an existing 4x -R strat.
Unless you’re comfortable with manually editing a firmware with a hex editor, I would not recommend this.
