I did a manual re-tune this morning and was surprised to find lots of stations still in the 800's. So I did it again and I'm getting stations from channels I haven't selected. To test it I did an auto tune and cancelled it - no channels. Rebooted and checked in the webif to confirm. Then I tuned JUST channel 51. Checked in the webif and it is showing channels for 24,27, 28 and 51. What is going on? I've done the same retune on both my HD's with no issues.
