[mythtv-users] Getting this working should NOT be this hard!

OK, I'm trying to get my TV channels and such setup in MythBuntu 8.04.1 
and I'm having a TON of problems.  I switched to MythBuntu because of 
everything I've read, and its all been "its worked right out of the 
box".  Not for me!  Here's what I have going on, and hopefully someone 
can point me in the right direction.

I have a pcHD5500 card, and a Comcast Motorola DCT-3412 STB with 
Firewire.  I setup my pcHD5500 card as the required 2 inputs (Analog for 
2->99; DVB for the rest), and I have the Firewire box setup properly 
too.  MythTV Setup sees all devices fine.  I had deleted all of the 
cards earlier and rescanned for them because I wanted to start fresh.  I 
just upgraded the kernel thinking that might help some of my tuning 
problems that I'm having below.  I am using 2.6.24-21-generic on x86_64.

Anyhow, here's where my problems start:  after I setup all of the cards 
and scanned for channels accordingly, if I go into MythWeb and look at 
the channel editor, all of my Analog channels are on SourceID 1, the 
Firewire are on ID 2, and the Digital (DVB) are on ID 3.  Not a major 
issue, but my Backend status page says I have encoders 5 -> 7.  Where's 
1, 2, and 3?

Next, when I try to tune an analog channel, it may or may not come on.  
If it does, I get a picture for a second, then the screen fills in all 
green, then back to a still picture, and so on.  The audio sounds almost 
like what you'd hear if you put a baseball card in the spokes of a 
bicycle tire.  In my backend log, I get alot of these errors:
2008-10-16 21:39:07.217 NVR(/dev/video0) Error: Resetting and re-queueing
2008-10-16 21:39:09.218 NVR(/dev/video0) Error: DQBUF ioctl failed.
                        eno: Input/output error (5)

If I tune a digital channel (via DVB), I get a picture, but its VERY 
slow.  Almost as if I have a TiVO or Comcast DVR recording playing on 
the slowest Fast Forward setting.  Again, the audio is the "baseball 
card in the spokes" analogy.

If I tune a firewire channel, I get a frozen picture followed by a 
message stating "You should have gotten a signal lock by now...".  No 
audio is heard at all.

I can try and capture a small AVI video clip of what I see and post it 
somewhere if someone cares to see it.  I just can't believe that 
something so seemingly basic, and apparently being used by TONS of 
people, just doesn't work.  I'd say that I'm missing something, but the 
whole point of using a pre-built distro was so that wouldn't happen.

Any ideas?

Thanks,
Harry
