I was recently looking into this as well, and found this:
http://forums.steampowered.com/forums/showthread.php?t=683570&page=3
The specific solution: if you comment out these lines from the server
player
.cpp (sdk_player.cpp, for example):
SendPropExclude( "DT_BaseAnimating", "m_flPoseParameter" ),
SendPropExclude( "DT_BaseAnimating", "m_flPlaybackRate" ),
SendPropExclude( "DT_BaseAnimating", "m_nSequence" ),
and
SendPropExclude( "DT_ServerAnimationData" , "m_flCycle" ),
SendPropExclude( "DT_AnimTimeMustBeFirst" , "m_flAnimTime" ),
the choppiness goes away. Not totally sure of any unintended consequences
of
this, though.

Subject: Re: [hlcoders] Choppy motion using the 2007 sdk mp template
Alright, I've found a couple of related threads in the archive, but they
are
unsolved:

There's an apparent fix in that second link but I noticed it's already
included in the SDK and I still have the issue (would hate to see what it
was like before!). Another curious thing I noticed is that when driving a
veihcle this problem doesn't persist, movement is smooth. Surely, I can't
be
alone with this, because I think it's very much an issue with the sdk
code.
Anyone?

The SDK Skeleton does seem like an interesting starting base, assuming
it
doesn't have that problem - but I think it might be a little too
stripped
down for my needs (seeing that it can't actually start a playable server
or
do anything by default). Unless perhaps that was just something I messed
up,
but I get this error:
Client missing DT class CWaterBullet
Host_EndGame: CL_ParseClassInfo_EndClasses: CreateDecoders failed.
Dropped Player from server (Disconnect by user.)
What codebase is this intended to be compiled with? Because, I see that
it
includes a 'vgui_video.cpp', which isn't in any of the 2007 SDKs I
pulled
from Source SDK (source code only and mp template) - Ended up removing
it
because even by including the file (thanks Google), there was a link
error
for it.
Anyway, it would still be nice find a solution back at the template
mod -
I've tried messing with the rates and interp console commands since the
rates seemed a little low, but I still get the same effect. Reading up
on
interpolation though, it sounds very much like what the problem could
be,
only I've no idea what to do about it, since I obviously won't be
understanding that completely, as a beginner.

Someone else was talking about this a while back, I think it was
related
to interpolation. I don't recall the fix, but I do know that the SDK
Skeleton player doesn't have the problem.

On that subject, an Alien Swarm version of the skeleton is nearing
release. There's only multiplayer ragdolls left to get working. :)

Well, I noticed the problem in the beginning - so yes, I am
experiencing
this in a clean base - 2007 multiplayer template, only fixes are
compile
fixes, release build, default game directory (appid 218), etc. One
strange
thing I noticed is that while playing is choppy, if I record a demo,
on
playback it will be super smooth as if there wasn't a problem at all.
It's
as if the client isn't properly syncronized with the server, while
playing.
I don't know, but I've had some other people try it out, and they have
the
same problem, too.
Also, sorry for breaking format, I assumed receiving digests would
still
send my threads back individually - not the case :P
How much and exactly where have you been "toying" with your source
code? I
assume you're not experiencing these issues with a clean,
unmodified 2007
scratch or template build?
