Here in Schaumburg, SciFi, USA and Discovery are all tripled onto one frequency. I've heard Comcast is using a form of compression (they call it something else) to do this. It's obvious that during fast movements it cannot handle it and starts stuttering or showing major breakup. Worse, this seems to affect the other two. So far, Discovery only seems to stutter, but I haven't seen it pixelate.
In some other forums, people in Michigan and elsewhere have also seen these issues. It's possible it's uplink issues (USA and SciFi are both part of NBC/Universal). We'd need some satellite users to compare against. Another possibility is Comcast is using a master site to compress them, then distributing that feed nationally.
For the audio issues, if you have a DVR, you can try one of these 'fixes':
Pause for a few seconds, then play so you are buffering
Use Review to jump back 15 seconds, then LIVE again.
I think with the new software we got in November that LIVE is pretty much LIVE (anybody with both a DVR and non-DVR to compare?) I've noticed that when I do a pause on many channels, it seems to back up a second before finally pausing. I think when you then go back to LIVE it's actually the old 0.5-1 second buffering.
