I've only just discovered xmltv.co.nz yet it looks like it's been around for while...
Has anyone had any success converting this source (or others) to MXF using xmltv2mxf (http://code.google.com/p/xmltv2mxf/)? By the looks of things it's designed to work with xmlTVNZ, I've tried it with the haventech and pvr.geek.nz sources but gave up in favour of Bigscreen EPG due to the pain of manually adding Sky channels and ending up with a completely munted EPG. Bad WAF given the struggle I've had migrating to 7MC from an old S1 TiVo.
Keen to hear other's experiences with xmltv2mxf, xmltv.co.nz, and grab a copy of Channels.xml from anyone who has all the Freeview and Sky listings configured :)
