@tmm1 and @maddox -- I think there's a little bug in the current pre-release server. I don't think it's my links or site.
I can set both PlutoTV and Stirr to update the EPG every hour, but the server is only actually calling the EPG links for one EPG or the other -- it's as if there's only one wake timer being set, and it's either PlutoTV or Stirr, but not both (unless a manual update is forced).
For instance, I had both set to update every hour. Last night I noticed that Pluto hadn't updated for several hours, so I did a forced update, then it started updating every hour, but then Stirr stopped updating. I got up this morning - Pluto updated every hour, but not Stirr. So I forced a Stirr EPG update, and Stirr updated once, but it's still only updating PlutoTV.
The Channels log reflects this, there is no "Fetched guide data for XMLTV-Stirr in 0s" entry between 9:24pm yesterday and 7:10am today, while there are log entries for PlutoTV.
I installed the non-pre-release server on a different computer to test the three-hour update, but that's going to take all day to test.
