Sky Sports HD - Weak signal but ALL others ok!?

[Stuza]

Hey Guys

I use the Dreambox solution to grab entitlements and pump it through to the 7MC box so I can watch Sky. I've recently built a new box to do this and have now discovered a rather odd problem!

ALL channels work fine EXCEPT Sky Sports HD1,2,3 and 4, which all appear to have a weak signal, which of course, doesn't make sense! Any ideas or would this more likely be an issue for DVBLink to help with (its using TVSource)?

Thanks in advance!!!
