As one of the best alternatives of Windows Media Player, Real Player usually can do a better job. Since it supports almost all known video formats, you have to transcode some of them to iTunes accessible file types. Besides, the preloaded online video downloader usually delivers tons of MKV files in HD quality, which may also give you great headache. And following video formats are supported BY Real Player NOT BY iTunes: rm, rmvb, flv, 3gp, 3gp2, wmv, avi.

Make sure your videos are NOT supported by iTunes!

If your source video is in MP4 (MPEG-4 or H.264 video codec) format, there is no need for this tutorial since iTunes can playback them natively. RM and RMVB are two popular file types on Real Player. You can find a Video Converter tool to transcode your source video to MP4 format.
