Yip I have. I've set it to import automatically to WMC, and to match channel names automatically. And it seems to be doing that correctly, since all the channels have data added to them.
I tried setting up the DVBLink plugin, but it never found any EPG. I used exactly the same parameters (I think) as otherwise, but when I run an EPG collection, it tells me that despite finding all the channels, it found no EPG data.
EPG Collector assumes that it is collecting all the data in the guide so before it imports it clears all the flags/indicators in the programs and channels in the MC database so if you then only collect 3 channels (ie you have excluded the rest from the collection) only programs for the 3 channels will be colored until TVSource collects again.
As far as the plugin is concerned, if you choose to pass the data direct to TVSource it will show how much data it found. If you choose any other method (xmltv or direct into WMC) TVSource reports that no data is found because the TVSource developers haven't provided the plugin with any means of indicationg it has finished correctly but passed no data. In these circumstances the only way you know it's worked is by looking at the MC guide or the EPG Collector log.
