ArizonaSteve - On LiteON PC based bruners you use the booktype135 running in the background ....put a +r dvd in the PC burner, start booktype135, do a query, it'll show up as a +r, then change it to dvd-rom...it'll say booktype changed successfully..now MINIMIZE, DO NOT CLOSE the booktype135 program and use your burning software to burn the dvd...when the burning is done maximize booktype135 and do a query again the dvd will now show as dvd-rom.
