[mythtv] Filter interface change proposal, working on patch.

> I read the rest of your email, but I have to ask.  Why not just get two
pchdtv cards?

A dozen hdtv channels at most, cable will remain an analog source for a very
long time. If I could junk analog recording, I would.

> My point was only that, *I* was pretty happy with low res quality from a
bttv card, especially if I had been able to run the denoise filter.  Bumping
the quality up to 720x576 is not a huge quality difference (well actually on
my card it did, but on my card recording on high res and then rescaling down
was better quality than simply recording on low quality ... I assume my
drivers have an issue...?)

PAL I assume? NTSC is only 480 horizontal lines, and with cable it's
actually a lot less, capture resolution won't change that. I assume it's
much the same overseas, PAL spec's at 576 lines but the actual program
resolution is less. Capturing high and resampling low serves as a good noise
filter as well, because it serves to average out interference.

> So I think there are two classes of user here.  Those who want super high
quality, and those on a budget (plus those who have no choice...)  In the
UK, DVB cards are £60, which is not much more than a bttv card, and so
although I have a bttv card I haven't even bother to plug it in.  I have a
P2.8, but I've still taken the bttv out of  the machine and put in a second
DVB card because of the low CPU use and much higher quality....

> So to recap: For those at home thinking about using Myth, you get a
*really nice system* using just a cheap bttv card, especially if you are
just viewing the output on a TV.  However, if you are looking to fill a huge
tv/plasma/projector, or you want low cpu usage, then look for the
PVR/dvb/hdtv cards.

In a perfect world where we could get all our current programming by just
using digital signals..... My goal is to have broadcast/cable tv look better
than it did when it came into the building, for everyone if possible. (It
already does for me right now). I think your two classes of users don't
exist, only users with more or less money. I doubt filters will be much of
an issue where people can get DVB.
