So far the biggest mistake I have made was selling my Buzz 4500 before getting a chance to use the P6. I ordered mine the very first week, and It has brought no extra functionality, but has brought along a long list of bugs. Now it may be my provider, but I have never had all these issues with the 4500. If a Mod wants to know what provider I am using, please private message me, it is a stalker only provider.
I know you will not let us know what provider you are testing on, so it will be hard to measure Apples to Apples... but here are my gripes:
PVR never worked well on the 4500 (Buzz4 or Buzz5) but it is no better on P6 (Buzz5 or Buzz6)
lacking PVR, my next best way to watch shows in the past is catchup.
That worked 95% of the time with the 4500, I am lucky if it works once in a week on the P6. Always getting stream error. I regularly talk to the guy I sold my 4500 to and another friend with the same 4500, and all three of us are on same provider.... And only the P6 is having all these issues
I never get buffering on either of the units (4500 or P6), and I have pure fiber internet, and I am running through a dedicated VPN.
I am seriously considering an older Buzz that may be a bit more mature. Maybe a Series 5 or even an older 4500, and wait a few years for the P6.
I know you guys are working hard on this, but for the price... It has been a very frustrating experience.
Thanks Steve
