    Re: Hauppauge HVR-2250 woes

    When my sister got her PVR from Time Warner they had to give her 1600mhz splitters for just that reason (she couldn't get any high def channels at all). That's why I ran the cable from the living room, since the TV works for sure (off a 1600mhz splitter). The splitter off the cable modem in here is one of the 900mhz ones, which this morning I realized might be a problem. Tomorrow, or the next time I get to work on this, I am going to put the card into the Windows 7 machine again and see what's what with the cable from the living room.
    I'll report back what I find.
    I really appreciate all your help!!

    be carefull not all splitters are created equal. If you can stop by your local cable company support building and ask for one, they might just give them away, or charge you a few bucks... but they are well worth it.
    Last night I lay in bed looking up at the stars in the sky and I thought to myself, where the heck is the ceiling.

    That's a great tip! Thanks.

    Re: Hauppauge HVR-2250 woes

    Ok, I am back, had a busy week!
    So I ran the cable from the same splitter the TV uses and put the card back in the Win7 box for testing. After it not being recognized (??) and reseating it in the slot it now sees all the channels the TV does and then some. I am able to watch all the unencrypted ones no problem. I replaced the 1600Mhz splitter with a 2400Mhz one, and it tested out the same. I learned from this that Metrocast uses QAM-256 for sure.
    In the interest of troubleshooting, I read that Kaffeine would be good for testing. Earlier (I think it was before the driver update, but not sure) I was getting a "device not found error" when I would try to configure it and scan for channels. Now it scans and sees the channels and I can watch them (although the sound is broken on the HD channels).
    Put the card back in the MythBuntu box and go to do a scan under Input connections and now it is scanning! Cool!
    So then I get this error when I go to watch TV:
    mythtv is using all inputs but there are no active recordings
    So I ran:
    sudo service mythtv-backend start
    and it says it is already started.
    So, then I do this:
    sudo service mythtv-backend restart
    And now the error is gone. I have to do that after every boot.
    But, when I go to hit a channel that has info for it, I get an error about channel lock, and it says Signal 0% Partial Lock.
    In MythWeb I get this though:
    Encoder 1 is local on Dionysus and is watching Live TV 'Back to the Future Part II' on 2066. This recording is scheduled to end at 5:30 PM.
    So what could I be missing?

    Edit, one channel is actually coming though, but now when I try to switch I get an error "Error opening jump program file" and it boots me out of LiveTV.

    This sounds like the same error I got when I first tried my digital tuner in a new Mythbuntu setup. It was caused by running out of kernel memory. Check your backend log (/var/log/mythtv/mythbackend.log) when you get that error, and see if you see any errors referring to memory allocation failing. If you do, check /var/log/messages for errors referring to vmalloc.

    If this is what is happening to you, the fix is here:
    http://www.mythtv.org/wiki/Common_Pr...lloc_too_small

    If this isn't your problem, then check both the frontend and backend logs for other clues. Feel free to post your logs here.

    Hope that helps...

    I didn't see anything in the mythbackend.log or in messages about vmalloc (except the normal message) but in the frontend log I get this when it happens:

    So, I am thinking it's due to "Signal 0% Partial Lock" and therefore generating no file for the frontend to read? Kaffeine plays all the channels normally (well, the sound in HD is messed up, but one thing at a time).

    There should be something in your backend log about switching from None to WatchingLiveTV. The transition from Partial Lock to Lock is done in the backend, so I think your problem is in the backend, not the frontend. I think your best clues to solving your problem will be found in your backend log.

    You might want to post both your frontend and backend logs in the MythTV-Users mailing list, where users and developers with much more MythTV experience than I have might be able to help you.

    Re: Hauppauge HVR-2250 woes

    Ok, these weren't the only problems I was having with Mythbuntu, there was a bunch of other things like the restart button just logging out, weird permissions things, MythWeb stopped, and the backend quit starting up at boot. etc. I felt like it was whack-a-mole. Every time I went to do something I would have to fix something else first.
    So since I have 3 machines that run flawlessly on plain Lucid, I started over, but installed Lucid (not MythBuntu) first, then installed all the MythTV packages. I followed LowSky's instructions on his other thread to get the card to work and everything almost works now. I just have to tweak all the settings for my display.
    That's for the help, I really appreciate it!

    Re: Hauppauge HVR-2250 woes

    I was able to get an HVR-2250 working on Ubuntu 11.04 2.6.35-24-generic by substituting the basic hg clone / make / make install with something a bit more complicated but ultimately successful for me:

    Code:
    0. `sudo apt-get install v4l-conf`
    1. `hg clone http://kernellabs.com/hg/~stoth/saa7164-v4l`
    2. Use this as v4l/.config: http://pastebin.com/4GPrszBV
    4. `make`
    
    5. For all files with implicit declaration of function 'usb_buffer_free', add the following to the top after the #includes.
    
    #define usb_buffer_alloc(a, b, c, d) usb_alloc_coherent(a, b, c, d)
    #define usb_buffer_free(a, b, c, d) usb_free_coherent(a, b, c, d)
    
    6. Repeat steps 4 and 5 until you no longer encounter the 'usb_buffer_free' errors.
    
    7. You should now encounter the 'struct net_device' errors. Download the full linux-source-2.6.35, decompress it, and copy the following to the v4l directory.
    
    linux-source-2.6.35/drivers/media/dvb/dvb-core/*.h
    linux-source-2.6.35/drivers/media/dvb/dvb-core/*.c
    
    8. `make`
    9. You may encounter more 'usb_buffer_free' errors, if so, repeat steps 4 and 5 again until it goes away.
    10. `sudo make install`
    11. `sudo modprobe -r saa7164; sudo modprobe saa7164` or `reboot`
    Here is the relevant section of the kernel log after the modprobe: http://pastebin.com/rWB6WBhB



    Hope this helps!
