Roamio Losing Channels Intermittent and Hiccups
I'm having a problem with a roamio (4 tuner) where I will intermittently lose channels, Besides not getting the channel if I try to move forward or back and it skips the channel all together. The channels that are lost will be random. My signal strength is 80-90 and I am on comcast with a cisco Scientific Atlanta cablecard (PKM800) with lastest firmware. I have an amplifier and 4 way splitter in house that was installed by comcast. I can get the channels back at times by using Signal Strength under setting. When watching the Roamio we also occasionally get what I call a hiccup where the video freezes for a second with audio loss and then it continues.
My other Tivo HD-XL is working fine without problems.
I'm trying to decide if the problem is due to one of the following:
2. Tivo Hardware (Bad Tuners of HD)
3. Comcast Signal
I suspect the problem is the cablecard but the hiccup makes me think it could also be a hard disk problem.
