can anyone tell me how to create a such xml file that can be used.
I downloaded the xmltv 0.5.51 but I guess I have no clue what to do with it.

You could try using Couch Potato (http://www.patrickpatoray.com/index.php?Page=101) but the problem is it's for US and Canada and it's using SchedulesDirect, (a paid service), which is in violation of their service agreement in that you can't use SchedulesDirect with EyeTV, even through XMLTV.
