Well I have now uninstalled this patch. It seems to have some serious issues and on top of that does not fix the NZ epg
I have had the following problems.
Recording failing to record
Corruption of the recordings database
and very very slow response when adding or removing recordings (suspect this is linked to the database corruption)
The third issue was fixed immediately after uninstalling the patch. I will have to see how recordings go before saying that the recordings are reliable again.
