Why is it that the FW and FR work only with mp3's. These functions don't seem to work with .wav, .m4p, .aac, .flac, etc. Why is that? I think this is an important function.

This is a FAQ, frequently asked, and frequently answered question. Have
you done a trivial search of the forum history?

I have done a trivial search and found that these buttons work for some people and not for others. I didn't notice anyone mentioning a specific format that worked or a specific format that didn't work. I was trying to clarify that. Thanks for your response.

From the Beginner's Guide in the wiki (http://wiki.slimdevices.com/index.cgi?BeginnersGuideToFileFormats):

Native or Transcoded?
In the Slimserver/Squeezebox world, this can be an important difference. The various models of Squeezebox can handle different file types internally, so given (for example) an MP3 file can decode it into music within the box. Other file types can't be handled within the Squeezebox and are "transcoded", i.e. decoded in the Slimserver into another format that the Squeezebox does know how to handle (see also: Transcoding). SB2/3 natively handles MP3, WAV, AIFF, FLAC and WMA (except WMA Lossless): earlier models just MP3. See HardwareComparison.

Another significant difference for a Squeezebox is that you can fast-forward or rewind with a format that can be played natively, but not one that is being transcoded.

So, it's not only MP3s that can ff/rew, but any format that the SB can natively decode.

That's close, but not entirely true.

(warning, excessive detail ahead!)

For example, SB2/3 now supports OGG/Vorbis as a native format, but due to implementation details FF/REW still doesn't work for those file types (see http://bugs.slimdevices.com/show_bug.cgi?id=3809). Also, FLAC is a native type and normally supports FF/REW, but not if the user has their music in the "one file with cue sheet" format. In that case the server is actually doing a FLAC/FLAC transcode which prevents seeking (see http://bugs.slimdevices.com/show_bug.cgi?id=1426). I'm sure there are more edge cases.

Thanks for the replies. These two explanations were lucid and helpful
