For those following the Mishna Yomis learning schedule, you may want to check out the Mishna Yomis site on the Shema Yisroel network. Every day there is an mp3 audio file, which you can play on your computer, for the 2 Mishnayos for that day. The lecturer is using Kehati's commentary and speaks fast enough so that he covers the 2 Mishnayos in about 5 to 7 minutes. There is also a huge archive of 50 of the 60 Mesechtas in Shas, so you can use for any other Mishnayos learning you may be doing.
