#10774: Maximum of 5 simultaneous recordings per tuner is too low

I have a TBS6984 quad tuner satellite PCIe card, which says that it can
record up to 12 HD channels per tuner:
http://www.tbsdtv.com/products/tbs6984-dvb-s2-quad-tuner-pcie-card.html
Why is it, then, that when running mythtv-setup to configure the backend,
the maximum number of simultaneous recordings per tuner is set to only 5?
Note that the BBC/Sky in the UK have launched 24 HD channels on satellite
to air Olympics events - with the card I have, this would limit me to only
20 of the 24 :-( Also note that I have an i7 CPU and a very fast Intel SSD
(500+ Mbytes/sec write) which are needed for such a large number of
simultaneous recordings.
Nearly a year ago, there was a similar complaint on the official mythtv-
users mailing list:
http://www.mythtv.org/pipermail/mythtv-users/2011-June/317125.html
As you can see from that mailing list posting, the change is a single
hard-coded value in videosource.cpp. Although their suggestion to raise
the limit to 20 is arguably too high, my suggestion is that you raise the
limit to 12 instead, since I've provided the URL of card that can record
exactly that number.
I would also suggest adding something to the setHelpText() call along the
lines of:
"Do not set this value above 5 unless you have both a fast CPU and fast
SSD for recording."
Although ideally, you want that in a warning dialogue if it's set above 5,
but I don't know if you can do that.
