    I can't seem to get any video

    Hi all,

    I've been using Mythdora 3.2 for several months now but just bought a new 750gb hard drive and thought what a great opportunity to upgrade. Tried to upgrade to Mythdora 4 but ran into problems and so stumbled upon Mythbuntu. I really like the look so I have decided to run Mythbuntu if I can get it all working correctly.

    For whatever reason, I can not get my video to play, all I get is what appears to be scrambled input. It's not a black screen, not static, no squiggly lines. I hope that makes sense.

    This is my hardware;

    ASUS A8N32-SLI Deluxe mobo
    Hauppauge pvr-500 capture card
    Nvidia 6600 video card
    1.5gb RAM

    All this hardware worked fine while I was running MythDora 3.2. I bought a new hard drive but since I've been having problems, I put all the original hardware back together because I know it works.

    If I pull my video in from my capture card and plug it directly into my tv, i get cable just as I should, so i know the set top box is providing a good signal.

    I've been pulling my hair out for 2 days now but I'm still no farther along. I did a normal Mythbuntu install, nothing fancy, nothing unusual. Perhaps it's ivtv drivers? Tried using tvtime but still same problem so my hunch is it's a driver issue.

    Any help right now would be great. Mythbuntu looks fantastic! Great job on the interface and install scripts, etc.

    I guess I should also mention that I have my schedule direct account set up and working properly. mythfilldatabase has run and I have data in the database. If I hit the 's' key while in watch tv mode, the schedule listings come up and I can change channels.

    Thanks,

    Tim

    ivtv module

    the ivtv module does not seem to be loading. From this page http://ubuntuforums.org/showthread.php?p=3989685 I found this,

    =========================================
    To make sure that the ivtv-fb module loads without errors, in a terminal window, do

    lsmod | grep ivtv_fb
    to see whether the module is loaded. If there is no output from the command, the module is not loaded. In this case, execute

    sudo modprobe ivtv_fb
    =========================================

    lsmod | grep ivtv_fb gives me nothing so I tried sudo modprobe ivtv_fb and got the following error.

    twooten@leo:~$ sudo modprobe ivtv_fb
    FATAL: Error inserting ivtv_fb (/lib/modules/2.6.22-14-generic/ubuntu/media/ivtv/driver/ivtv-fb.ko): No such device

    Any ideas??

    Thanks,

    Tim

    Re: I can't seem to get any video

    I've got nVidia problems too. Used to work out of the box in Edgy.

    I boot up Gutsy using the "nvidia" driver, but just get a black screen. The "vesa" driver works fine.

    I'll post if I find a solution.
