Ritek G05 is DVD-R not DVD+R.
Being from the UK, you have probably never tried TY media as it is pretty spendy over there. The cheapest I found TY in the UK is Fuji re-labeled TY +R media. 7.34 pounds including VAT for a 25 pack or 29p per disc. Not bad for high quality media. While it is true that there is no 100% media, TY definitely stands out from the rest in terms of overall compatibility. I can't tell you how many modded/unmodded XBOX, PS2s, DVD Players, ect. that I have used TY on and it has worked and always burned at the max rated speed and I am just one of many users on countless forums who have reported the same thing. There is just too much evidence out there of TY's consistancy with quality and compatibility for me to use or recommend anything else (although Ricoh and MCC/MKM are excellent alternatives if you live in a country where TY is too expensive).
