Strangely, with enough futzing around, it started working. I don't know
what I did. The last thing I did was reload the msp3400 module on the
backend, but I am running the frontend on a different machine, so I
can't imagine that affecting it.
In any case, it does seem to have cured the jitters!
I get a very slight amount now (usually only when I start mythtv or
change channels) but once it gets going, it is much much smoother.
There is still a very short pause in the sound every once in a while,
but I have not yet sat through a full show to really evaluate it.
With OSS, there were time, that I could not even watch it was so bad,
like continuously stuttering....
So if you have sound problems, it is definitely worth the effort to
update to alsa.
I would be interested to know if the slight jitters I hear, like when
changing channels, is normal.

I am using v.93c. My frontend machine is an Athlon 2200+ but I am
planing to put it on a VIA M10000 when I can get one. The VIA mini-itx
boards have hardware decoders, so I am hopeful it will be fine. I can't
imagine it is cpu power though.
Are you running front and back on the same machine? Does your CPU do
mpeg encoding, or are you using a hardware encoder? Does it jitter with
prerecorded programs? What is your cpu?
