This is the best type of media I encountered so far. The are DAXONAZ1 (DVD+R) sold as BENQ in jewel box, made in Malaysia. The quality seems consistent among the batch I have. There were on sale with about $1.05 / piece. I never saw such a scand with my drive (Teac W58GA = LiteOn 812s) and I tested so far Imation, Verbatim, Traxdata, TY, Maxell, Panasonic and other less known.
See for yourself the scan.
