I have used 6.02 for a long time, and recently swtiched to 6.1 (currently 6.12). About the time I installed 6.1, I installed Windows Media Player 9. I run XP with all current patches. We play a lot of sounds in the channels I'm in, and all mp3s have sounded horrible (high pitch distortions) since I went to 6.1, and mp3s encoded under 128kbps are completely distorted and unintellegible. wavs & mids play fine.
I'm not familiar with how mirc handles sounds, but i've tried playing the mp3s that mirc wont play in Winamp & WMP 9, and it handles them fine, so what exacty is playing mp3s in mIRC, and why isn't it working anymore? does it use its own player? I need to get this fixed

if somebody could point me where to change the player or file association I'd appreciate it!
Thanks in advance for your help!
