Hi

I'm setting up a Knoppmyth box for my parents for a christmas gift. I've got everything working but the following:

1. IRBlaster. I tried following the instructions here http://www.blushingpenguin.com/mark/blog/?p=24 , but they seem very vague to me. I have the send_power_new script, and it does turn on the power to my satellite receiver at some point, but I have no idea how to tell which codeset it uses. The script doesn't display anything when run.

2. Screen position/sizing. The display to the tv has some empty space around the edges. Not just when watching tv, but all the time. I have no idea how to fix that. Though I'd found it in the TV settings, but it just made the tv image 'zoom in'.

3. Mythweb. This is probably a total noob question, but how do I log in to this? What username and password? Not even root lets me in.

I have a hauppage pvr-150 with the latest version of knoppmyth (r5d1 i think) If anyone can help me out here, I'd be really appreciative. Thanks

userID is "mythtv" password is the password it prompted your for during the install (after software suspend, and irblaster questions). If you don't remember post back, I have it documented somewhere how to clear the password.

Are you using an nvidia graphics card with either svideo or composite output to a TV? If so, run nvidia-settings and adjust the overscan.

Well Mythtv worked for the login.. I could have sworn I have tried that before And I am running nvidia with svideo out, so I'll try the settings right now, thanks

The overscan worked nicely. Cut off a bit too much, but it's better than seeing empty space Now I just need to get the IRBlaster working and I can wrap this thing up! Thanks a lot for the help so far.

The overscan works, but it resets every time the system is rebooted.
Also, I still need help with the IRBlaster please. I only have a couple of days left, someone pleeeeease help!!

Have you searched forum? If I recall correctly, you have to save settings and have nvidia-settings restore when you reboot. Another option is to use TVOutOverScan (if I remember correctly), you can see this in the sample nvidia XF86Config-4 in /etc/X11/.

Thank you very much. The overscan works perfectly.
Back to just needing the IRBlaster set. Anyone?

what kind of IRBlaster are you using and what are you trying to control (make/model)? There are entries on the wiki for a generic IRBlaster and the one that I use, the actisys 200L. Make sure that your serial port is enabled in the bios and set to the correct com port that you selected in irblaster setup. My bios lets me set that port to com1 or com2 (even though there is only 1 serial port on there).

Troubleshooting tip: Use a digital camera, phonecam, or camcorder to see if you're getting any output on the IR Blaster. This works with any IR remote. It's invisible to you, but a camera will show it as a bright white light. Just like a flashlight. Use the "live preview" mode, and you will see if it sends a signal or not.
Here is a picture of me showing my son how it works:

I'm using the IRBlaster on the Hauppage WinTV PVR-150, so not a serial port. I know it's working, because I can run the send_power_new script, and at some point the satellite receiver does turn on, I just can't tell when, because the script doesn't show me anything when it's running.

Im not familiar with that IRblaster. Can you do ALT-X and run the script from command line? I think that maybe your using the wrong codeset that is being sent to your cable/sat box. Id try searching the mythtv forum or even google? ße sure to also look for your specific cable box. Mine, the echostar 311 uses a strange set ofcodes. Try the LIRC site too.

After a whole lot of trial and error, I found the codeset. I can send the commands via command line manually, and the receiver responds properly, but I can't get the change_channel script to work. I have it in /etc/change_channel I put that in the 'run external command' in mythtv-setup, but it doesn't actually do anything. I'm so close!

1) Make sure to use the full path name, i.e. rather than just putting "scriptname" in the field put "/usr/local/bin/change_channel.sh" or whatever the exact fully qualified name of the file is... Remember in Unix/Linux, case matters.
2) Make sure the script is set executable. (chmod +x /your/scriptname/here)
3) Make sure that the script has the proper #! (pound-bang) magic on the first line. E.g. "#!/bin/bash"
4) Make siure that the script returns "success", which in shell is an exit code of zero.
5) Add a debugging log to the script so you can see what it's doing (advanced topic)
