XML guide won't show and causing high CPU load

Hmm, so just read the issue ‘Progam guide information in New Zealand (NZXMLTV)’ which didn’t stand out to me as being related as it specifically names New Zealand and should be renamed. I live in Australia.

So it would seem this is related to DST which also fits into the time frame I first observed this issue as well. Looks like this is a common ongoing issue.
I’ll re-add the DVR once the issue is resolved. Can’t risk burning out my server or setting my house on fire until then.
