I bought a roamio vox OTA and it works great. I added a mini vox from best buy and it gets through the setup and fails. I go on tivos website thinking maybe I need to activate it but it says box is already activated? I call tivo and they give me some bs about the boxes from best buy have a software glitch or something (she didnt sound like she had a clue) and they are not sure when it will be fixed. I get error s308. Sorry for the long post, just wondering if anyone has experienced this? Thanks!
