You can lose bits but if you have managed to get into such a totally
pathological situation you won't have much problem knowing it; Randomly
corrupted bits are pretty obvious.  But 'audiophiles' blathering about
jitter just don't know what the heck they are talking about so you can
safely ignore em.  They are usually the ones with tube amps, thousands
of dollars of cables, etc.  If you have a totally braindead DAC at the
end of that toslink or spidif you might get jitter but good luck finding
something like that in 2013.  What you will more likley find is an amp
that captures that bitstream, does additional DSP processing upon it in
ram and then outputs it to a DAC using it's own clock.  For most MythTV
work the bitstream being sent is compressed multichannel audio that will
need decoding anyway so it is digital data and not even a plain
digitized waveform.
