yahoo broadcast/msie/ms media player questions

two week long reader/new poster/ordering soon pb15"

situation- i am going to be transferred to afghanistan (kabul) and am looking for a new computer. planning on an apple for recording some music and what not. i also would like to listen to my college teams football and basketball broadcasts on the net.

on yahoo's site ( http://media.yahoo.com/ncaa/splash/learn_more/sysreq.html ) they list the requirements as

IE 5.2 or later for Mac
OSX 10.2 or better
WinMP 7.1 or WinMP for OSX

No other alternatives listed.

I ask these questions because I see very little if any discussions about them. While I am familiar with IE and WinMP for PCs but not for apples.

Any issues with using them on an apple? Major conflicts? Will it take control and never want to relinquish its functions? I'd prefer to use the built in apps rather than add ons at first but the sports radio stuff is important to my sanity (or will probably be, I am told).

I'm a newbie and am slightly confused by some of this has I have pretty much only been exposed to windows products. I was recommended to macs because of the music capabilities and durability.

Thanks-
