Yes - I am aware of the strong recommendations to Verbatim media in these forums and I appreciate your advice. I like Verbatim media - but their DL media is very expensive, so I decided to experiment a little with 1 or 2 other brands. I expected to make a number of coasters before finding success. But, as it turns out, it worked perfectly - I expect thanks go to LUK's ImgBurn - and Benq's wonderful 1655 burner. I have a small supply of this Ricoh 8x DVD+R/DL media - and we'll see if the rest of it works as well as the first. Thanks again.
