What brand of media are you using ? I know you mentionned further RICOHJPN, but they are sold under what brand ?
Are you putting an adhesive labels on them or writing on them with a marker ?
How are they stored ? (room temperature, cold, warm, sunlight, etc....)
Are the discs scratched or dusty ?
I have burnt litteraly hundreds of DVDs with my 811, I think well over 300 since many people come to me to have their tapes transferred to DVD, and I can tell you that one year and a half later all of my personal DVDs play just fine on all 3 DVD players I have.
As long as you stay away from no name brands and cheap media you should be fine. RICOHJPNR01 is reliable media and long lasting (probably will outlast you....) so there should not be a problem.
As far as LITEON blowing goats, I would not go as far as saying that, as I consider it a very good drive, as long as you use quality media and avoid the crap. There are many advantages to LITEON including high quality and highspeed CD writing, fast ripping and handling of copy protection (3sheep+), etc.... I do however fully agree that LITEON needs to pull their collective fingers out of their arses and improve their drive and provide better QC......
