hello,
i have bought a medialink challenger from the sponsor.
when i'm scanning for channels it comes up with 'SVC_0543 SERVICE' with loads of different numbers for different channels instead of the proper name like cartoon network etc...
also i cant view the channels as it looks like theres something wrong with the signal or something as the screen is mainly dark then i get a broken picture?

i cant workout why these wont scan normally,...i've used network scan, blindscan etc and they just wont scan.

any ideas please?
thanks in advance.
