Okay some remarks on all the stuff.
First the 3 best dual format dvd writers.
Well the 3 best dvd writers based on writing quality articles comming from different sources are:
Pioneer A06 - Best overall media support.
Plextor 708 -Less media support as Pioneer but the big names seem to perform slightly better and it has 8x DVD+R for 4 media (Only a serious option with MCC 4x media) . Most -r media that isn't supported has luckily proofed to be not the best stuff out there. Still some media could be better supported
LG GSA-4040B -A nice drive with tripel format suport. And excellent OPC at 2x. However -R 4x support is very limited to recommended media.
If your not ussing recommended -r media then there is a good change that your media will be burnt fine but only at 2x.
-R only
If people are intersted in only burning -r then buy the a05 it is even better at the a06.
The 3 poorest in random order dual format drives out there.
Sony DRU 500- Since it was the first dual drive. It might be logical that it gets it spot here.
Sony DRU 510- Tough choice between the NEC- N-1300 and this one. Why it's construction is better. It's firmware and firmware support isn't.
Sony hardly implemented support for new media and the old firmware shows also some weird behaviour. If this drive had better firmware support it wouldn't be at this place however in this case it's here.
Lite ON 411S - Lite On's attempt of a dual format writer. It's media writing quality has problems. A lot of pro-lite on people say well it's the media.
However with firmware FS02 it was not the case. Since it showed problems with Maxell and MCC manufactured media. These 2 manufacturers have proven that there -R stuff is as good as the +R media so in this case it isn't the media. The bigest problem seems that the drive seems to burn -R media that is quite incompatible for some reason (jitter /Assymetry). So far data on 401S have indicated that laser power is to weak and for this reason it's Assymetry turns out bad. This might be even more worse with -r media on the 411S. The ability to burn media is quite good however the playback with -R media really is problematic compared to the competition.
I think there's a good change can fix this with firmwares that is if they want.
Now some reactions

I think the media companies need a year to catch up. Although, if ti wasn't for the drive makers forcing the issue, media companies might never make the needed improvement.
I haven't seen any comparisons of burn time on a 8x CAV drive compared to 4x CLV, I wonder how much it is....
Well media compannies are allready working on it by themselves but if some people want to go faster then the competition it works out differntly.
Infact quite some manufacturers are not changing there road map and for that reason there isn't 8x media arround yet and the drive manufacturers had to optimise 4x media to burn at 8x. MCC is allready working on faster media and materials for third parties to make -r media easier (Good -r Media in this case 8x media will be easier to make with the new stamper )
8x CAV, well +R should be able to make the move quite easilly compared to -R. Fact is that CLV is a easier mode to implement for quality cd burning as CAV. That's why Z-CLV is back. I think implementation of CAV technology for 8x writing would have returned in the media being earlier there as the drives.
rdgrimes on Lite On 411S
I don't see any write-quality issues, I see crappy media issues
Sorry but with FS02 the performance on Maxell and MCC shown different.
But the newer firmwares might have changed it.
