yea...mpeg4 audio is not part of Real. It is just a supported format. Personally I am a fan of BSPlayer but to each is own. And if you have some stuff that really is RealPlayer only...you can always use the RealAlternative CODEC and play it in any media player you want. Now if you want your buttons to work in LS I think you are stuck with using WinAmp, iTunes or WMPC for all your needs.
