Plextor 712A, Firmware 1.05. It can play storebought audio cds fine. It cannot play mp3 cdr's (burned at 52X, Memorex CD-R) which my cdrw can play. Is this to be expected? WinXP Home, tried WMP, Media Player Classic, and Ultraplayer.
Is this to be expected?
No ... but can you be more specific? Did you use File|Open with MPC/WMP, and what did they say when you tried? Can you read the directories of these discs in Win Explorer? Are the burns any good (try C1/C2/CU scan in Plextools)?
My bad, it was bad burning on my part. I downloaded some mp3's from another source and burned them. I tried the two cd's that would not play in a portable player and they did not play.
