If you have any series records set up, you may want to check them NOW.
As you all probably know, the ABC changed it's channel allocations yesterday and IceTV updated the channel name and number information in the guide because of this.
I found that I neither had to rescan nor reorder my channels (ABC was still on the same MC "channel" as was ABC2 and ABCHD) but I did had to reassociate the channels with the guide. And not just for the three ABC channels - all the HD channels were also listed as "No Data Available" and had to be reassociated with the guide. Not a major task, BUT reassociating them with the guide
broke the link to any series recordings set up for these channels. I missed one show last night as a result

and had to go through my HD series recordings this morning, delete them and recreate them from the guide so the would work.
I have no idea why IceTV would play around with the guide aside from the three ABC channels, but they did. Worse, their official notice anly mentioned changes to the ABC stuff, so we weren't even aware of the possibility of problems with the commercial HD channels. Shame IceTV, shame.
In summary:
- Check you have guide information on all your HD channels
- If not, reassociate the channels to the correct guide information
- Then check your HD series records are actually finding their shows. If not delete and set them up again.
