EPG Collector 3.2 is now available on Sourceforge here.
https://sourceforge.net/projects/epgcollector/files/V3.2/
It is 100% compatible with v3.1 so would advise everyone to upgrade at some stage.
For NZ terrestrial users the tuning files are up to date to the end of March 2012 with the frequency changes that are being made. For frequencies after that date that will be changed there are 2 sets of tuning files containing the old and new frequencies so when you need to change just load your ini file into EPG Centre, select the new tuning file (the name is annotated to enable you to identify the new frequencies), set your new frequency and save the parameters.
Also for NZ terrestrial users who want to import directly into Media Centre you should NOT use the 'Automatically map EPG data' option but map the EPG data to the channels using Media Centre. You must also set the new option on the Output tab to 'Create data for channels with the same name if data not present'. If you do not do this you are at risk of losing channels from the Media Centre guide.
