If your blocking/freezing issues are signal related, you should see it in those numbers being too low.
Since I have that 8300HD running MDN (is that the same thing as the "non OCAP" box that Rob referenced? - I have trouble keeping these abbreviations straight in my head), this sounds like a good diagnostic method except for one thing...
I've never seen this issue (the freezing of a program for 20 or 30 minutes mid-stream) on a live broadcast where I can look at the signal strength in real time. Why? Because we never watch anything live, not even sports. Every time I've experienced this, it's been on a program previously recorded, although at times it may have happened to a program I've been "chasing" (watching an earlier segment from the DVR's buffer while the program is still recording). I think. Hard to remember, exactly.
Basically, I was just wondering if anyone else out there has experienced this problem. Then, if so, we could compare notes and see if a logical explanation bubbles to the surface. 'Cause right now, I got nuthin' but frustration and whenever I get a TWC tech out to look at the signal strength, it's fine. Of course. They have no other explanation, either.
I sure don't want to get rid of my box because, even with the aggravation of TWC's refusal to update the Navigator MDN software (I've discovered workarounds for the bugs and learned to accept truncated program info and the ancient 4x3 GUI), I love my box. And I especially
love the 750GB expansion drive that's hooked up to it that gives me the freedom to record whatever I want, whenever I want, and keep it as long as I want. That's all good.
