I?m ripping DVD audio files to WAV format while also converting & sending WMA files to my MP3. I used to think my FXemail@example.com could easily handle almost anything, but I?ve been experiencing slow downs since using the WMA format for my MP3. So I checked the CPU usage in Task Mgr and it?s often constantly pegged at 95-100%. I used to rip to MP3 320kb without any lag. PC is still responsive, just a bit sluggish." Is this normal for a FX-55?
