Ok, finally have my new box built (see http://mysettopbox.tv/phpBB2/viewtopic.php?t=8433 for details) and I'm getting ready to install Knoppmyth and purchase the necessary cables for to interface with my system.
I have a question regarding being able to control my DCT-2524 box. The cable will come into the box, and I plan on using the s-video out and sound out to my PVR-250 box.
Can someone confirm that my thoughts are either right or wrong, and if wrong, give me some hints to the "right" way:
1. To change channels I will control my PVR-350 using the remote and receiver that came with it.
2. Using lirc and an IR blaster connected to my serial port and after proper configuration, it will send the proper codes to the DCT-2524 and change the channel.
3. To record a program, lirc and IR blaster will change the channel on the 2524 as Myth tells it to.
Is my understanding correct?
TIA!

I am in the same situation and have 2 add on questions regarding this.
1. my comcast service has encrypted QAM. I've looked around and I'm pretty sure using a cable box and IR blaster solves this. Am I correct?
2. can you still scan the channels when the cable box is sending the signal to the computer? won't it just find one channel? When I look around, most people are just talking about using the firewire (which I don't want to do).
i'm one of the "very new" people, but i'm having fun figuring this out and reading up on it.

Well, I have the box up and running. All I need to do now is get the IR Blaster and run a network cable into the living room.
I'm currently just using my cable box to change the channel and running in the s-video from it to the PVR-350. Works good enough to get me by for a bit.

Well, I have my IRBlaster from http://www.irblaster.info/ (very quick service by the way) and I plan on hooking it up this weekend. Does anyone know of a howto for controlling the 2524? That would be great!
Also, I solved my ethernet cable "issue". I purchased a Wireless "Game" adapter, which is basically a wireless to ethernet adapter. Works great by the way! 
TIA again.

I had all of my IRblaster stuff working until I started testing something a few days ago. Once I get it sorted I'll put together a relevant howto.

Here is how I have done it
Things to NOTE I have 2 PVR250 cards if you have one change the lirc2 lines to lirc1
if you want my change_channel.sh script and lircd.conf file PM me with your email address and I will send them.
tar -jxvf lirc<tab> #it will auto complete
change directory to the newly made lirc.0.7.2pvr150 directory
cd /usr/src/lirc.0.7.2pvr150
run setup
./setup.sh
Here I am going by memory but choose serial then
transmitter and software generated
then menu item 3
then
make
then
make install (I realize the version in KnoppMyth has serial support now but I recompiled anyway)
In your /etc/modutils/lirc you'll need something like
Code:
alias char-major-61-0 lirc_i2c
alias char-major-61-1 lirc_i2c
alias char-major-61-2 lirc_serial
options lirc_serial irq=3 io=0x2f8 # for COM2
Update modules.conf
Code:
update-modules
Then in /etc/init.d/bootmisc.sh put something like
Code:
/sbin/modprobe lirc_i2c
/usr/sbin/lircd --device=/dev/lirc --output=/dev/lircd
/usr/sbin/lircd --device=/dev/lirc1 --output=/dev/lircd1 --pidfile=/var/run/lircd1.pid
/bin/setserial /dev/ttyS1 uart none
/sbin/modprobe lirc_serial
/usr/sbin/lircd --device=/dev/lirc2 --output=/dev/lircd2 --pidfile=/var/run/lircd2.pid
You'll also need to make the extra devices in /dev
Code:
cd /dev
mknod /dev/lirc1 c 61 1
mknod /dev/lirc2 c 61 2
lircd will be your first x50 card, lircd1 will be the second and lircd2 will be com2
Make a "/etc/lirc/lircd.conf" file that includes configurations for both devices (remote and set-top box) by concatenating the two configuration files together. For example, if your set-top box file is "stb.conf" and the file for your remote is "remote.conf", then:
Code:
cat remote.conf stb.conf > /etc/lirc/lircd.conf
(save your old lircd.conf first)
Make a channel changing script "change_channel.sh" for use with Mythtv
Code:
#!/bin/sh
STB_NAME=XXXXX
for digit in $(echo $1 | sed -e 's/./& /g'); do
irsend --device=/dev/lircd1 SEND_ONCE $STB_NAME $digit
sleep 0.4
done
irsend --device=/dev/lircd1 SEND_ONCE $STB_NAME SELECT
Note: replace "XXXXX" with value from the "name" line in the lircd configuration file for your set-top box. Put it someplace useful, like /usr/local/bin and don't forget to make the script executable by all.
12. Run mythtv-setup to tell it to use "change_channel.sh"
REBOOT

You'll still need a valid DCT-2244 file to cat into your lircd.conf. Here's my entire lircd.conf (this assumes you have an irblaster AND a pvrx50 with the silver remote).

Correct me if I'm wrong - but will this allow you to access the cable menu for Comcasts 'On Demand' stuff? Like the pay per view stuff?
And if that is the case - how could I get the codes for a DCT-2000 digital cable box?

If you read near the bottom where the code is commented, you'll see a mention of the Comcast On Demand button..which is just controlled by sending a 1 to the box then an enter. In practice it may be different however, so you may need to experiment.
For the remote codes for a DCT2000 box, I suggest a little googling for 'lirc DCT2000'. There's a master lirc site that has all known and decoded codes for hundreds of set top boxes.

Thanks!! 
I've been thinking about, and getting confused about, getting this to work on a setup where there is a backend server which controls multiple cable boxes and a frontend at each tv. I get lost in trying to figure out how to get the correct signal to the correct cable box. Theoretically, a frontend will get any available cable box.... 
Any hints as to how I might configure that??

I imagine since you're following a lirc thread that you're trying to do this via either infrared (ir blaster) or serial. Basically your backend, which I'm assuming has multiple tuners plugged into your multiple cable boxes, will need to control each box individually.
Personally I haven't gotten in this deep yet. I know that you can set recordings and priorities to use specific inputs (tuners) but not sure how the frontends treat the backend when it comes to this. Perhaps frontend A controls backend tuner A all the time, or each frontend that requests a channel change will check to see if any tuners are on that channel already and start the stream.
I know something like this is definitely doable and probably much simpler than I'm making it out to be. I'll wait for someone that's more experienced with multiple backend tuners and frontends to fill in the blanks.

Like I said, I'm getting confused myself.
I'm actually using a serial cable to control the tuner boxes. I have 5 tuners in the back end, two just taking an anolog cable signal (basically straight from the wall - no tuner box) and three taking a digital signal from the cable boxes. One of the boxes is an HD box. The analog tuners can tune the channels directly from the basic analog signal from the wall, so I'm fine with those. It's the digital boxes I'm confused about.
My understanding, though limited at this point, is that the front end passes its commands to what ever tuner it has control of. The backend manages what available tuner gets assigned to the requesting front end.
The system is not completely setup yet, although I'm able to watch any tuner and record multiple signals simultaneously. I have a frontend setup and am able to watch/record from it, but I haven't got it traversing menus from the digital cable boxes.
Still a work in progress - but it's coming along slowly.
