I cannot be the ONLY person on planet Earth...but here goes. Upgraded to Roamio. Attached adapter (Motorola - firmware updated yadayada) and I get the SDV channels. Then...I leave a SDV channel on a tuner (either taping while I am out or just leave it on before bed) and I wake up and "Tuning Adapter Missing) and the adapter is blinking. Third adapter btw. So basically the adapter keeps failing and the tivo sees the adapter is missing so it stops everything and no longer records - it just stays on the missing screen until I tune back into the SDV channel and the adapter re-sets. I can be watching an SDV channel and the same thing happens - the missing adapter error pops up and I lose all SDV signals (and the adapter is blinking). I realize that the SDV channel times out -- but that shouldn't crash the adapter. I just wish an angel would hear my cry for help. Because TWC does NOT understand my problem and TIVO suggested I give up. TWC blames Tivo. Tivo blames TWC. I have loved Tivo my whole life but the end is near. Please tell me I am NOT alone. It would make the pain easier.
