I used to be able to rip all my cds to WMA, but switched to MP3. I tried\nswitching back to WMA, but I get the message "Windows Media Player\nencountered an unknown error. This can occur when another program or\noperating system encounters a problem but does not communicate the nature of\nthe problem to the player." I have also deleted music that was originally\nrecorded as WMA, but now they won't record as anything but MP3. I am able to\nuse the variable WMA rate, but not the regular WMA. I am currently using WMP\n10.00.00.4074, Windows XP Media Center Service Pack 3. Any help would be\nappreciated. Thanks!
