actually i think Prodisc are supposed to be rather good, as a "second choice" brand, after the first tier: Taiyo Yuden, Verbatim/Mitsubishi Chem., Mitsui.
if i hadn't stocked up on Verbatims i would probably buy that 50-spindle of 24x Samsung myself.
my burner is a Plextor 40x, i haven't burned any Prodiscs on it (yet). sorry can't help.
according to the Media Compatibility With CD-RW Drives
thread, some Samsung Prodisc 24x burned 40x on Lite-On 48125W and 52246S drives.
