I don't use eyetv that frequently so can't really say when this started happening. I did a rescan earlier to refresh the channel list & noticed BBC 4 HD & a few others are missing.
It looks like all channels on Com8 are missing.
I use an HDHomerun. I've tried eyetv 3.6.9 7520 & 7528. HDHomerun’s own software works fine & my PVR (using the same Aerial) picks up the missing channels fine.
The channels are not found in a rescan but are still present on another machine that I’ve not performed a rescan on for a while. Tune into BBC 4 HD (for example) on this machine & the channel displays briefly before showing ‘No Signal’. The audio continues to play. If I set the channel to record, the video plays back fine.
Checking the signal meter in Preferences reveals 100% signal strength, but 0% signal quality.
COM8 has recently started broadcasting as a single frequency network & I think I live close enough to two main transmitters to pick up at least a bit from a secondary. Maybe eyetv doesn’t like this? I think the same is true for Com7 though and the channels on that mux are fine.
SD & HD channels are both affected.
