This is probably your problem:
I 22:51:15 Media Type: DVD+RW (Disc ID: RICOHJPN-W21-01)
Since this seems to be the first write operation you've performed to this DVD+RW after formatting it, you've no experience with these media before? What's most likely the problem is your LG, and I think it's an LG burner, doesn't like those particular brand of Ricoh/Ritek DVD+RW.
My LG had no problem with writing to 8x Ritek DVD+RW (It would Verify some discs that were obviously corrupt enough they wouldn't play properly, but that's another story.) but I don't know about your drive/media combination.
Where I'd go from here is try some Verbatim DataLife Plus DVD+RW. I doubt Traxdata is of very high quality, as Ritek/Ricoh is a 2nd tier optical disc manufacturer. Don't get Life Series Verbatim. DataLife Plus Verbatim media can only be found online. I only use my Ritek DVD+RW because they're the only ones who made 8x DVD+RW, and now no one does.
