I know that the file types you are trying to play are
Real Media, and Windows Media Player. They are owned by other companies, and not open file types. There might be a third party player for them, but Apple has no plan to buy the ability to play those files. The iPhone does not like to play Flash files either which is an Adobe file format.

Best bet is to look for those files on itunes, or reburn your music using itunes. Although apple does have its own file type, AAC, it generally tries to be friendly to open file types and play them without a problem.

You windows computer might be able to take these file types and make them into something more apple friendly.

Otherwise get a windows phone. The new ones maybe yet to be available her in Qatar are pretty cool, and likely for a cheap price.
