I'm using a Plextor 755UF (external, connected via Firewire; FW 1.07) and PlexTools Xl 3.12 to burn my discs. I'm also only using ultra-certified DVD media (Verbatim, Plextor-branded TY; burning Plextor/Verbatim CDs works fine) but I'm getting mixed results.
I'm mainly burning DVD disc images on +R/+R DL media with the following settings: AS: Auto; Powerec: Enabled; Write speed: as per disc certification (16x; also tried 8x, I would even select lower speeds if this means better quality). Curiosly enough, AS creates a new strategy even when using certified discs at the recommended speed! I called Plextor and they said this is a strange behaviour, because AS is not supposed to create strategies for known media. This has been happening with FW 1.06 and now with 1.07. I also removed previously created strategies but AS goes on creating them. For example:
Media was bought from Plextor recommended resellers, so I don't think it's phony.
Regarding DL media, I'm only using Verbatim 2.4x media which, unless specified by me, is burned at 6x with good results; if I select 2.4x (with PoweRec ON) recording is done at 6x (max write speed) - 2x (last write speed) but the disc is poor and cannot be read by a standalone DVD player. When I selected AS OFF, assuming it would use the strategy in the FW, I got a coaster.
Bottomline: I'm only interested in quality and dependability, that why I bought Plextor + quality media--speed comes a good last. At the moment, I'm not getting it.
What's your opinion?
Thank you very much!
