MCE set-up comes up with all unknown channels

[SGSMikeG]

Hi,
I'm setting MC up and it detected a whole lot of channels which came up as 'Unknown Channel' with a frequency in brackets.

My building (in Sydney)has a UHF/VHF/Digital Antenna.

MCE detected the following channels:
# Frequency Actual channel
1 64250 2 - VHF
2 182312 7 - VHF
3 196312 9 - VHF
4 209312 10 - VHF
5 527312 SBS - VHF
6 653312 2 - UHF
7 674312 7 - UHF
8 695312 9 - UHF
9 716312 10 - UHF
10 737312 SBS - UHF
11 786250 PRIME (Wollongong) - UHF

How do I edit the channel names ?

I have HP M7188a Media Centre PC which has a hauppauge PVR500 dual tuner card in it.

Regards
Michael
