I am posting this as i hope that somebody can help me. Tivo technical service cannot and even as I try to find people with similar problems in the community my case seems special.
I am using a Stream with a Roamio along with an Apple Airport Extreme router. Until a few months ago all was great - I was able to download every show to my Ipad or stream outside the house. Then all of a sudden the only feature that would still work is the inhouse streaming. Every show, even the stupidest, became grayed out for download as well as out of house streaming. The message is "Download not permitted - Due to copyright restrictions, downloading is not supported through external devices".
When I bring this up to Tivo they are telling me it's my router, I have verified that NAT-PMP (Apple's UPNP) is (and always was) on; they have me run all kinds of checks for port settings (which all pass), but they are ignoring the fact that my in-home streaming actually still works and that all of this used to work also out of home.
On the flip side, I have checked the CCI bytes on the relevant channels and they show 0x00, which suggests that they are not copyright protected.
At the same time, I wouldn't put it past Comcast to put these kind of restrictions on Tivo so they can push their inferior X1 product.
I am really at a loss and despite escalation at Tivo I am unable to find a resolution to this problem. Also searching on the forum and the internet at large has not brought a solution.
Hope to find somebody out there who can help me.
