    Hello,

    I am suddenly receiving "Invalid MAK" when trying to decode the latest episodes of Survivor. The first couple episodes work w/o a problem. Did CBS or tivo recently make a change to the programming that prevents tivodecode from working?

    I've been using my setup for years and never experienced this problem prior. I use Galleon to move the episode to my Linux server then decode it. I am not experiencing this with any other programming.

    I am using tivodecode v 0.2pre4.

    I searched Tivo Community forums and Google and didn't find an answer. Anyone experiencing a similar problem? Suggestions?

    Thanks,
    JoeK

    Odd indeed... I just started getting the same thing on an old EpixHD recording. Is it date related? Perhaps a cert expired somewhere?

    In any event, using the -n option to turn off MAK validation appears to do the trick.

    Sinanju,

    Your suggestion fixed the problem - thanks for your help! I hadn't noticed the "-n" parameter prior. It's been awhile since I've written my scripts and didn't think to check for options to tivodecode.

    I still wonder what's changed. Much appreciated!

    Hi guys-

    I'm getting the same error regarding "invalid MAK".
    I would like to try the -n fix and I found the main script file, but I am not experienced with changing a script, I'm not sure exactly where the "-n" goes.
    Could you help me out with a more detailed description?

    Thanks in advance.

    @dstahl67, the command line usage for tivodecode is listed below. In your script find the tivodecode command and add the -n parameter to that line by following the format below. Make a copy of the original script before making changes.

    Usage: ./objects.dir/tivodecode [--help] [--verbose|-v] [--no-verify|-n] {--mak|-m} mak [{--out|-o} outfile] <tivofile>

    --mak, -m media access key (required)
    --out, -o output file (default stdout)
    --verbose, -v verbose
    --no-verify, -n do not verify MAK while decoding
    --help print this help and exit
