Khun 715 is much faster and more precise than my typing and I saw it right before I post my long and winding one. Let me add something here which is still relevant, IMHO.
It is my understanding the digital cable broadcasts its signal in composite format and the DsTV by UBC uses the Digital Broadcasting Service which broadcasts its signal in separate chroma and luminance format (Y/C).
While UBC doesn't tell exactly which technology they use, I make a conclusion after reading all the link below. I found resemblances between DBS/DTH (I recalled once that UBC satellite was called DTH which seemed to be another name for/implied DBS technology) such as the frequency used (Ku band) and the size of the satellite disc (small disc 1-3 feet vs. huge disc that you need to install it on a lawn).
As such,
1. For those
satellite subscriber to UBC, you should go for
S-video cable.
2. For
digital cable subscriber, it will depend on
the quality of comb filter of your TV vs the cable box. My guess is the TV’s prevails but you have to test it by yourselves for a final result.
If the TV has a 3D digital comb filter on PAL

in Sony HR, HZ and top of the line Panny, then the TV has a better comb that set top box. So you should use comb filter in your TV to separate (comb) the chroma and luminance signal from each other by stick to composite cable

Canare L5 series.
However, your projection TV seemed to have only a regular digital comb filter for PAL (likely a so-called 2D as manufacturer usually advertises very clear about a better 3D if they have it).
If you don't want to do the test and

me to guess, my money is your TV to have a better comb filter. Again, I would prefer you to do the comparison and let us know as it's more accurate that way.
