Point your dish at the satellite (no I'm serious!)

Circularly-polarized signals *are* receivable on any linearly-polarized
LNB; however, by adding a depolarizer, one *can* gain an additional 3dB
of signal (i.e. double it).  However, you need to say just whereabouts in
the Uk you are located.  By L/R signals, I presume you're atlking about
Thor and.or TV-Sat.  There have been reports that signals can be received
reasonably well on dishes as small as 1.2m in the extreme east of
England, and reasonably well in much of Scotland; OTOH, Bob wil tell you
what, whilst he can see TV-Sat on his 3.1m dish, the 2.5 jobbie is pretty
useless (and that's in the Midlands).

So just *where* are you?

This then would mean you have less chance of getting zapped the older a
card release is, since the database is growing all the time. And with so
many people taking on promotions and then most likely cancelling, the
database should be swelling up quite a bit.

Your right of course, I was getting confused with the number of 74h
packets that result in a 78h packet for decoding.

It certainly can't hurt to try....for now.
