would this be faster than the CYTA midrange broadband service?

Hi, I am totally new to this forum.  We live in Vergina and I am trying to obtain UK TV via my computer and at the moment I have CETA broadband which keeps freezing and often does not even load.  I use a portal system that I subscibe to and can get BBC iplayer and the ITV version, but I can hardly watch anything.

My broadband states that it is 54.0Mbps when I highlight the icon at the bottom of the screen, so I am not sure what 2Mbps and 4Mbps relate to with Cablenet and Primtel.

I have enquired with both companies to see if they have their service in this area and they both do.

So would I be better off getting cablenet installed?

We have only been in this house since July 1st and had to have CYTA reconnected from our other place.  We have kept our same phone number, but really need to get the TV sorted out.  We did have a dreambox system before, but it is no longer available so we have been told, so the only way we can get UK channels with a huge Dish is from the internet.

So can someone please suggest a reasonable system that will do the job with costing a fortune each month?

Thanks in Advance
