Patent Restriction Issues
MP3
MPEG-1 Audio Layer 3 (MP3), while commonly used, is recommended against. The format has patent and licensing issues in many countries. Unlicensed use of MP3 runs the risk of infringing in these countries. Licensing the use of MP3 costs at minimum royalties of US$15000 per calendar year.
MPEG
Other MPEG related formats are restricted by patents as well. Finding the prices of licenses for these formats is not even as easy as it is with MP3. More info here.
Recommended Alternatives
Free alternatives exist and are highly encouraged. These formats include Ogg Vorbis (lossy) and Ogg FLAC (lossless) for audio, and Ogg Theora for video.
