playback problem
 

Hello everyone. new guy here, so i'm not real familiar with the forum yet. hope i'm in the right place. I'm running vista, using microsoft's zune player, and limewire pro. had many problems getting all three to work together. what i ended up doing was removing all older verisions and replacing with the latest versions from the appropriate websites. everthings happy now, except, playback.
heres whats happening. I'll download (non copyrighted) music. playback using limewires player works fine. but when i open the library-explore folder and play it back, using my default player, which is zune, it sounds like a skipping record. anybody remember records? When i send it to my zune it will sound the same way. so I can't send any downloads to my mp3.
However, if I rip a cd or download from zunes site it sounds fine. hope this makes sense. more than that I hope someone can help me.
Again, Hello to all. will be visiting this forum often.
