While I am new to Channels, I've used HDHomeRun since it's beginning.
I have a HDHomeRun Prime and Apple TV 4K.
My proveder is Comcast digital so most channels are 720p resolution.
So far I have found the following guide data errors.
1205 ESPNHD USA
1206 ESPN2HD TNT
1207 NBCSNHD FXhd
1208 FS1HD SyFY
Also Mute by shacking remote does not work
Another thing on my server, an Qnap TS251 when recording CPU use is very high 70-90%.
Which seems quite high for only recording 1 channel.
Is there something else I need to do?
