Does anyone have any insight into this? I've seen numerous threads regarding the HD TIVO having stuttering problems. However, my problem seems to be only on ESPN HD - all the locals I get through the antenna, along with all other D* channels seem to be fine. Any idea why I'm having this problem ONLY with ESPN HD? And to top it off, it only happens during regular programming, and for some reason, never during commercials. It is pretty regular - it happens approximately every 2 minutes or so. Very annoying. Live broadcasts and if I have it taped on Tivo. ESPN HD only. Help?!?
