Unable to rip to mp3 in Microsoft Windows Media Player 10 (MP10)

Resolution :

Delete the following registry key:
HKEY_LOCAL_MACHINE >> Software >> Microsoft >> MediaPlayer >> Settings >> Mp3Encoding >> LowRateSample

Still not working?
Verify the encoder setting:

HKEY_LOCAL_MACHINE >> Software >> Microsoft >> MediaPlayer >> Settings >> Mp3Encoding >> PreferredCodecPath
C:\WINDOWS\system32\l3codecp.acm

Sometimes it is listed as l3codeca.acm instead of l3codecp.acm
