I have to say this: matsushita is who make the burners ok from the beginning of the technology (at the early stage) and yes, it's true that "you stand a better chance of being hit by a meteorite than getting a Matshita/Panasonic firmware update" i have to admit it. But I had the best compatibility from panasonic/matsushita drives (DVD burners at least) specially when i had to burn mediocre (crappy) cheap blank media.
Believe me smething, mate: Both crappy and medium quality media had horrible PIE/PIF scans when I burned with LiteOn, Samsung (mediatek), LG (renesas), except with Pioneer (NEC) or Optiarc (NEC too) ... this was hundreds of burnings and scans with multiple combinations of Chipsets, Brands of media, different firmware configurations, testing between MID from each blank media I put my hands on, and testing burns with each speed possible.
All this long and sad story to tell you: If in my country were possible for me grab that ''bad choice'' UJ240, I would buy at least three units for sure, with my eyes wide shut. One more word to say: I remember reviews from Sony burners (both DVD and BD) at very early beginning being built with chipsets from Panasonic/matshita, selling it at crazy prices and then change to Mediatek chipsets (lite-on rebags) cutting prices down and "working hard" coding a bunch of Firmware updates only to keep having horrible mediatek (LiteOn or Samsung) scans with my budget and 'medium quality' media (i.e. GSC003 - MaxMax brand 8x -R, CMCMAG??? 16x -R, and some TaiyoYuuden Fakes like the Picasso brand I have found in a 'ChiTown' mall in my city (Valencia -Venezuela-) all burned and scanned at every possible speed ) and having reading errors when played on consoles or movie players.
Yes, I know I am guilty for buying that pieces of sh*t. I swear I would buy all the premium Verbatims and Taiyo's you want me to grab, but I'll just say the vendors treat me like I was some kind of alien when I mention brands like these.
None of this happens when I recorded those 'cost effective' discs with panasonic/matsushita drives. I understand that the best many users can get is Pioneer (NEC), Optiarc (NEC), Plextor (NEC) etc, when it comes to DVD, and I totally agree with them. Still, as user of all these units, I regret not getting matsushita chipset units as easily as I would like.
