Hi Everyone, I have a DMRE-50 and I am happy with it however can anyone throw any light on the following: I bought 100 Unbranded Ritek DVD-R discs(silly I know, I should have bought a sampler pack but even then, the Ritek I was sent may have worked then I would still have bought the100) I got them from from dvd-and-media.com I have used 11 and already have 3 disc errors/coasters. I have tried the titling the disc first before recording onto it but that does not seem to make any difference. I have had no problems with Panasonic DVD RAM discs. Also the DVD's that have been recorded correctly play on my Panasonic RV32 player but will not play on my PS2, Samsung 709, or DVD Rom on my PC, is this the discs at fault or would any DVD media be the same regardless of brand? I only have these Riteks at present but recording is unreliable, but I haven't tried any others as I have so many of these. Does anyone know of a way of testing the disc first???
