Did so, but the result was (at best) an intermittent video full
of artefacts, with only some fragments of audio. Interestingly
it didn't make much difference even if I changed the srate to values
even further away from 2893. Only after going like more than
one hundred away did I get nothing at all.

I did also test whether I can sucessfully receive other channels
on S28.5E, and with

iBuy TV;BSkyB:12129:vC23:S28.5E:27500:2317:2319=eng:2318:0:7360:2:2022:0

for instance, it worked just fine.


So I'm afraid I can't confirm the theory the an "off by one" srate
causes the problem (at least shifting it by one didn't fix it).
