    Hauppauge HVR-2250 woes

    Ok, I am finally building my new MythTv box. I have everything installed including a Hauppauge HVR-2250 capture card. I used the tutorial here:
    http://ubuntuforums.org/showpost.php...&postcount=212
    And it shows up properly when I do lspci:
    02:00.0 Multimedia controller: Philips Semiconductors Device 7164 (rev 81)
    and in dmesg there are no errors:
    root@Dionysus:~# dmesg | grep saa7164_downloadfirmware
    [ 12.092542] saa7164_downloadfirmware() no first image
    [ 12.092553] saa7164_downloadfirmware() Waiting for firmware upload (v4l-saa7164-1.0.3.fw)
    [ 12.456759] saa7164_downloadfirmware() firmware read 3978608 bytes.
    [ 12.456762] saa7164_downloadfirmware() firmware loaded.
    [ 12.456771] saa7164_downloadfirmware() SecBootLoader.FileSize = 3978608
    [ 12.456776] saa7164_downloadfirmware() FirmwareSize = 0x1fd6
    [ 12.456778] saa7164_downloadfirmware() BSLSize = 0x0
    [ 12.456779] saa7164_downloadfirmware() Reserved = 0x0
    [ 12.456780] saa7164_downloadfirmware() Version = 0x51cc1
    When I add it in the MythTV Backend, all goes well, MythTV sees it and everything. But, when I go to add channels (i.e. Scan for channels) it finds no channels (Timed out, no signal) no matter what I set it to. I would think it would be Frequency Table: Cable and Modulation QAM-256 or 64 like it says in there. I know my provider broadcasts in digital as my TV scans them all fine. I also tried to just play the stream from the card in VLC but that comes back with:
    Unable to play the MRL 'dvb://frequency=0'
    With either input.
    Can anyone point me to the magic command that will make it all better?
    I do have ubuntu-desktop installed if that helps.

    Re: Hauppauge HVR-2250 woes

    Ok, had a bright idea. I took out the card and hooked up in a Windows 7 machine I have. Installed WinTV7 and had it scan for the various channels. It only finds about 5 channels around channel 77 when I scan for Digital QAM and none for Digital ATSC. It will find all the analog ones no problem (which I don't need (I have a PVR-500 for those in my current MythTV box), and the Linux driver doesn't support analog anyways).
    Now, right now I have my TV scanning for digital channels and it's finding all of them i.e. 6-1, 6-2, 8-1, 8-2, 8-3, etc, all the way up to 78 or so. They all come in nice and crisp on the TV.
    So, why the difference? I think I am missing something here. FYI- This is in Maine, US and as far as I know my cable company is running a standard setup.

    try a different firmware

    first open nautilus with Sudo privileges
    Code:
    gksu nautilus
    Go to the /lib/firmware folder and delete the file
    Code:
    v4l-saa7164-1.0.3.fw
    close nautilus

    download this file
    http://www.steventoth.net/linux/hvr2...164-1.0.3-3.fw

    then save it to /lib/firmware

    Code:
    sudo cp v4l-saa7164-1.0.3-3.fw /lib/firmware
    the reboot

    let me know if it works

    reboot and then try to scan again
    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.

    Re: Hauppauge HVR-2250 woes

    Ok, I tried that and upon reboot I checked dmesg and get this now:
    root@Dionysus:~# dmesg | grep saa7164_downloadfirmware
    [ 13.012034] saa7164_downloadfirmware() no first image
    [ 13.012042] saa7164_downloadfirmware() Waiting for firmware upload (v4l-saa7164-1.0.3.fw)
    [ 13.099219] saa7164_downloadfirmware() Upload failed. (file not found?)
    Do I have to change something else to recognize the new firmware?

    I just renamed to and now it is fine, trying a scan now.

    Now when I go to scan it fails to open the card.

    Re: Hauppauge HVR-2250 woes

    sorry I completely forgot. you will need to also run this part of my tutorial to use the newer firmware

    Next we need download the driver using these command to fetch and install, I'm using the stable branch from Kernel labs, but you can use Linuxtv.org version if you wish.
    Code:
    hg clone http://kernellabs.com/hg/saa7164-stable/
    now change to the directory:
    Code:
    cd saa7164-stable
    Then run the command make:
    Code:
    make CONFIG_DVB_FIREDTV:=n
    That will take some time, go grab a drink and wait it out, when it completes run this command:
    Code:
    sudo make install
    3b. Next Reboot the system to insure the driver and firmware are installed and running:
    Code:
    sudo reboot

    Re: Hauppauge HVR-2250 woes

    Ok, I installed the new firmware and it appears to be working, but it is still the same (Timed out, no signal) when I scan for channels. Even though I can get analog cable in here (office) I also ran a cable from the living room from the source that the TV uses to rule out bad splitters and whatnot.

    Re: Hauppauge HVR-2250 woes

    You will not get any analog channels using this card with Linux. The drivers do not support that. but you should see the digital.
    If you really do live in Shapleigh, Maine, then according to this link: http://www.silicondust.com/hdhomerun...lineup_2783452
    you can receive about 19 digital channels with cable (it says 34 but most are "on demand" channels) and possibly 23 using an OTA antenna.

    You say the card is grabbing channels in Windows and so does your TV, it could be the option your choosing for channels under MythTV. Check your schedulesdirect account and make sure you are only scanning for channels within the frequencies can actually receive without a cable box.

    Re: Hauppauge HVR-2250 woes

    I am sure about the digital because my TV picks up all of them. That's how I found out that they were even broadcasting in digital. I was playing around with the TV one day. It doesn't use a cable box, it's on a splitter with my old MythTV box, which is where my new MythTV box is hooked up now.
    I don't care about the analog as I have a PVR-500 (in my old MythTV box). I was hoping to get the nice digital picture.
    That chart isn't accurate as my provider is Metrocast. Most of the town is Metrocast, Time Warner is just one road on the other side of town.
    I had added the digital lineup to my SchedulesDirect account, and selected that one when I set it up in MythTV (my old box still gets the analog one), and ran mythfilldatabase.

    I also tried to "Fetch Channels from Listings source" but that doesn't do anything.

    I just did another Zip Code on that site, this one is more accurate:
    http://www.silicondust.com/hdhomerun...lineup_2789697
    WinTV on the Windows 7 box only sees the ones at the bottom that are Unknown (that might have been the cable in here which is why I ran it out from the living room). My TV sees them all. Rochester, NH, Sanford, ME all use Metrocast like I do.

    Re: Hauppauge HVR-2250 woes

    Just a bit of warning, digital tuners can be very sensitive. its basically all or nothing, not like analog were the picture will get fuzzy, digital will just not show up. Also when you split a cable line the signal is basically reduced to half. If you can use the cleanest possible cable line you can, hopefully one that hasn't been split.

    I had to have my cable company (Cablevision) update the lines into my house before we could recieve broadband internet, as the older line couldn't handle higher speeds, it was also providing substandard signal for TV so it was a great help when we also moved into HD.

    If I recall I huse CABLE-IRC High or something like that (sorry not at my HTPC to verify) to scan for my channels, most cable companies use QAM channels starting on channel frequency 70 or higher.
