Thanks to LG Electronics and the two reviewers in Seoul, I have already seen how LG's latest DVD Multi burner performs.

The sample drive was provided by LG Electronics in Seoul and Pyungtaek, South Korea. The files are hosted by me. Everything was done by Mr. kimya95 in Seoul, an SI admin. The reviews are all in Hangul, but there are also English, Arabic numbers, pictures, and tables.

The translation above was done by me. Upon request and degrees of importance, I'll translate the rest.
He gave nearly perfect score to GSA-4120B, 97 out of 100. The only thing he didn't like was its DVD ripping speed. DVD+R DL media was not provided as of this time.
Another review by Mr. innundo at SI is coming as well. He has already let me see his own media compatibility table. More than 100 media were tested. Since his workplace is right in the biggest computer market in South Korea, he's got some advantages. GSA-4120B could also write to That's YUDEN000T02 at up to 12x speed in addition to RICOHJPNR02. Verbatim MCC003 and RiDATA Ritek R03 only at 8x. I'm not sure whether it's also alright to link the review here. He'll decide.
I haven't contacted LG concerning DVD+R DL recording. Internal pictures will follow soon.
