I tested my live captures this morning to ascertain whether I could continue to use my iMac to capture NASCAR races. (This is what I have been doing. Seriously. It's a long story. It has to do with a mother's love. You may or may not understand.)
Anyway, the answer is no. Certain HD and standard channels, and their resulting DVR files, are now blocked on my DCT3416.
These channels are: 1) espn (standard and HD), 2) espn2 (standard and HD), 3) htv (HD), 4) uhd (HD), 5) yes (HD), and 6) tbs (HD).
Also, premium channels are also presumably blocked. I do not currently have premium channels, but I did once. A movie broadcast by HBO and and still resident on the DVR will not come off, just as my races taped weeks ago from ESPN are not transferrable.
Please feel free to draw your own conclusions from my test.
I did not power down my box as Hardcore suggested. I probably should have, but after I ran through most of the HD channels it became clear that certain things are now blocked and therefore nothing is wrong with my box. In fact, some would argue it is working correctly now.
The most humorous facet of the affair is this: When my husband saw how much work goes into transferring these files and burning the DVDs he told me I was nuts. "Go buy a DVD recorder for the tv," he said.
And another lesson hits home. But, a few questions first: Can ESPN/Comcast block a recording to DVD of a live program transmitted through a cable box/DVR? Can I copy my stored but now blocked DVR races to DVD in this manner as well?
Stupid questions, no? But I don't know the answers. Humor me with a response if you do. Otherwise I'm out 200 bucks.
