Looks to me like you hd3000 is working just fine, at least in DVB mode.  Your
problems now are mythtv/video settings and audio card settings. A good
way to test this is capture a video stream and play outside of myth, with
mplayer or something, and you may notice the playback is fine.

And, I feel yor pain.  I have a new Nvidia 5200 card and I get the same stuttering,
only within myth, even with low CPU usage (see my current e-mails since last 
night). Nobody has been able to help yet.

I pop my ATI 9600 card in - and everything is perfect.
