Recommend me a signal splitter

[androp]

I have line coming into my house going to a splitter,one feed going to my router one going to my gigablue box.
Im having trouble with HD channels glitching. Problem doesnt lie with the S***** as the sports hd are perfect just having problems with movies and some irish channels.
My S***** reckons the signal mihht be to week going to the sat/cable box and causing probelms.

Does this sound right or is there something else i should look at?
Ive done a new scan so all frequencies should be ok,
Im wondering would a booster help?

Thanks in Advance

try and get as official as you can for Cable these work well:

If you have a Gigablue Quad Plus with cable tuners then the Tuners are not great for a start off, I tested mine a while ago and while they cope well with a good signal a fringe one needs a better tuner

I have the 800hd se plus with sat and cable tuners can these tuners be upgraded to better ones?this only started happening recently,i thought tge splitter was failing but changed it and still the same. Could the DVB-C tuner be failing?? I dont see this could be as standard def channels work flawaless
