I've stopped using the T2200 and bought the Panasonic. So far I find it vastly more stable. I got sick and tired of the T2200 constantly breaking up the screen (the Panasonic and other previous devices like my Magic TV never did this and were perfectly fine, only the T2200 had a problem) and the fast forward and rewind always managing to get the sound and image out of sync. It's just crap hardware, don't even bother with it.
Your post gave me serious FOMO! I hate the thought of missing out on something better so I've done some investigating and read a lot of reviews on the Panasonic you mention. I liked the idea of the Netflix app and a playing from recorded content app, but I've come across several problems that would be a deal breaker for me. Are you able to confirm these previously mentioned issues with the Panasonic please?
Terrible remote control button placement
No volume on remote control
5 second delay often when issuing a comand, but no acknowledgement of command received, leaving user wondering if it received the request
Only padding available per episode (ie 1 min before, 5 mins after recording), not per series, so you have to pad for every single recording to make sure you dont miss the end.
When padding results in an overlap the padding occurs but does not record the 2nd show, ie cancels recording
A black screen regulary when Freeview +1 is enabled
Access via app for only 1 device at a time
