Roamio Plus 6 Tuner Question

Hi All - I am considering upgrading one tivo premiere 2 tuner to a Roamio Plus 6 tuner and replacing a Series 2 with a Tivo Mini. Hoping I can get a decent 10 year loyalty customer price on lifetime service.



My questions are:



Are there any known issues with 6 tuners. I had loads of problems getting all my Motorola Tuning adapter channels to come thru after adding my Moca network in my new home. The Cox Omaha tech determined that I was not getting a strong enough signal to the TA. I am concerned that if I move to a 6 tuner, I will have problems again with signal strength. Does the Tivo amplify the signal internally ? Wondering if others have had any problems with the 6 tuners.



Next, Does the Mini perform well over a MOCA network? I wondered if there was any lag using a tuner on the Roamio for the Mini and if there was any or much of a delay. I imagine there could be some for live TV. Can anyone share their experience.



Also, Is the Roamio harddrive upgrade process pretty straightforward? I upgraded hard drives in all my previous series 1, 2 and premiere tivos. I would plan to replace the 1 TB drive in the Roamio Plus with a 4 TB drive immediately.



I appreciate any feedback,

Thanks

Ken
