[mythtv-users] DVB-T2 290e Problem Tuning HD Channels UK Freeview.

[Ian Barton]

So I got my new DVB-T2 290e added it to the backend, did a complete nuke 
all channels and full rescan using the new card and found all the HD 
channels. For 24hrs I was a very happy bunny as I could watch and record HD.

However, suddenly the card couldn't find the HD channels. No amount of 
re-scanning, kernel downgrades, etc would make the HD channels re-appear.

I am in the Winter Hill reception area. I can receive HD fine by just 
using the TV. We have three aerials in the house and I have tested using 
all of them. I have tried the 290e on several boxes. All have the same 
result,  can tune all of the SD channels, but it doesn't find the HD ones.

If I run scan on the mux that has the HD channels I get the following 
errors:

Note I have commented out everything except for the T2 mux for testing. 
According to http://www.ukfree.tv/txdetail.php?a=SD660144 that data is 
still correct.

Can anyone suggest what has gone wrong?
