Is there anyway on the box to show the frequency or the UHF channel for a terrestrial channel?
Yes, but this is skin dependent. You will see the details in the service/channel list, not bouquets.
Just deleting bouquets won't help as the services will still be in lamedb. Enigma2 does not scan like TVs. ABM reads more than scans.
I think it will be best for you to flash Vix/PLI in one of the other slots of your receiver. When you are in the image, do not use ABM at all for freeview. change the setting "ignore dvb namaespace subnet) to no. Then scan. check all the services to ensure they work. You will have to use the service list/orbital method of channel selection instead of bouquets.
I never updated sutton coldfield properly as people on the other forum keeps mixing up how abm works with enigma2 scans. Every single flaming time. We might need to do the same thing as Manchester if there are different petals.
On your current image,
1. Remove services
Press Up (next to OK) on your remote.
Press the Green Button (Text may say Satellites, Extended or Simple).
Press up/down to highlight Terrestrial services
Press down and highlight "Remove selected satellite", " Remove cable services" or "Remove terrestrial services"
Then press OK and confirm the removal
2.
Unzip then transfer this xml file to /etc/enigma2
3. Reboot box
4. Set up Terrestrial tuner again. Select "Dr Box...."
It will have
<!-- Ch 39 -->
<!-- Ch 40 (HD) -->
<!-- Ch 42 -->
<!-- Ch 43 -->
<!-- Ch 45 -->
<!-- Ch 46 -->
<!-- Ch 51 -->
<!-- Ch 55 -->
5. Check customize menu and see if you can disable ignore dvb namespace subnet. Do not worry if you don't have it.
6. Perform a manual/complete scan on the USB tuner
7. Restart after it completes
8. Check all terrestrial services using the service list. ( just really need you to check one from each transponder, not every channel) Report back findings
EDIT:
If all OK, please upload your lamedb/lamedb5 files.
