The cable that you got is more than enough. Changing the cable is not going to enhance the PQ. If you want a branded cable then look for Belkin, Bandridge etc.
for a tatasky video....a belikin I say is more more more than enough.and a digital signal is 1 or 0...unlike analog..so for analog cable expensive makes sense...
I'm using a Belkin HDMI, I can assure you the quality is top. Don't go for over expensive cables. If you really fancy expensive one then go for DAC. I have used DAC analogue cables for 6 years and they are still in perfect condition.
