What bitrate is acceptable to play creative zen wmv. videos. I have converter the file from the mp4 to the wmv

First the player had me convert from mp4, mov. etc to wmv. inorder to recognize the file. Done. Then it says that it can not play with this resolution. So I change the resolution, now it is saying that it can not play with the bitrate. I don't know how to change that, what that is, or what bitrate is acceptable. I downloaded the videos from limewire and some of them play and some don't. Help pleazzzzzzzzzzzzzzzzzzWhat bitrate is acceptable to play creative zen wmv. videos.
