Pioneer is clearly a little better for Ritek burning and Princo burning and Pioneer has been the choice for most low-quality Taiwanese media.
Though the error rates shown are acceptable, none of the results are as good as those with MCC003 and YUDEN000T02. If you were using real MCC003, MCC004, YUDEN000T02, YUDEN000T03, TYG02, TYG01, and so on, you would be getting total number of PIF’s like 5 or 10. LG 4160/5160 + RITEKG05 at 8x showed over 1,138 and Pioneer DVR-A08/108 + RITEKG05 at 8x showed 411. And 8x is not a fast speed for 8x rated media.
I agree with you.
If you compare the prices of OEM Taiyo Yuden DVD media with REAL Ritek brand DVD media, there’s practically no difference. In some cases, Ritek costs more than Taiyo Yuden. Taiyo Yuden YUDEN000T02 branded under Fujifilm and Verbatim names are both cheap and good.
Right on supermedia.com page, MCC003 8x and MCC02RG20 8x are selling for US$0.3 per disk. Ritek 4x DVD media under them are selling for exactly the same price and Ritek 8x DVD media cost more.
Good Ritek media are sold under “Ritek” brand. There’s also RiDATA.
One of the good alternatives to Ritek average-quality media:
Verbatim 5-color 4x DVD+R media. YUDEN000T02 MID. Combines Mitsubishi and Taiyo Yuden technologies, but cheaper than Gigastorage, cheaper than Prodisc, cheaper than Ritek. Sometimes cheaper than Princo and Infodisc.
