I'm with Bright House in SE Michigan which is SDV. That said, I have a brand new Roamio Pro and Mini over gigabit ethernet. After going through all of my channels, I noticed 7 that tune and play perfectly on my Roamio, however they will not stream to my Mini or record properly. If I attempt to play these recordings back on either the Roamio or Mini, it's just a black screen. These are regular non premium channels: 224 - Fox News 270 - National Geographic Channel 286 - Fox Sports Detroit Plus 288 - Fox Sports 1 321 - Nat Geo Wild 322 - Fox Business 368 - Fox Soccer TiVo has no idea nor do I as to why the Roamio can tune these channels fine but can't stream or record them correctly. By the way, signal levels are great at around 80-85 with 35 SNR and 0 RS Corrected/Uncorrected errors. I was using this same Cablecard/TA with my XL4 and these channels recorded/played back fine, so I'm confident my Cablecard/TA are ok. Any ideas?
