Why I didn't think of this before, I don't know, but I need a little help if there's anybody out there who has the answer, please : I have 100 Infiniti DVD-R's (bought before I got my tosh). I have made quite a few DVD's on my PC, but NONE of them can be read on my Toshiba. However, they can be used in the tosh if blank and used to record onto by the RD-XS32. This suggests that there is nothing wrong with the discs themselves, but perhaps I'm doing something wrong on the PC. Is there anything I need to ensure is 'ticked' (or not as the case maybe) to ensure that my PC DVD recordings are compatible with the Toshiba?
