    Under what subsection do I put this?

    It does feel like a refresh rate issue that the bad frontend is outputting...the good frontend works just fine on the same TV.

    Why would you be embarrassed? You are one of the most (if not the most) helpful people in this whole forum.

    so...

    apt-get remove mythtv-frontend
    apt-get install mythtv-frontend

    ?

    I don't think I'll lose anything if I do that because it is a separate frontend and the only menu changes I make are made by a script that I created (and runs/checks at every startup), so...if that's what that thread is saying (and if you confirm it) I guess I'll give it a try....?

    Just slightly embarrassed I had forgotten about it...

    Take a look at your playback profiles and see if vdpaucolorspace is mentioned and try getting rid of it - that's what I took out of the other thread.

    removing and reinstalling the frontend package will not change the playback profiles - they are all stored in the database.

    vdpaustudio (level) has been removed as well, controlled from the OSD GUI..

    Why should un-used keywords cause such problems..rhetorical..

    ok, good to go! All vdpaucolorspace=auto has been removed from all 3 VDPAU playback profiles (slim, normal, high), and they all work.

    Sorry for asking a question that has already been resolved, but I guess it sometimes depends on the key words you use to search for it...I didn't know what to call it, so...

    Anyway, thanks!

    Re: vdpau black screen (monitor off) in mythTV

    I "upgraded" to 12.04 and the problem came back. "vdpaucolorspace" is not in the playback profiles this time.

    Any suggestions?

    Sorry, all of the playback profiles now have this issue. VDPAU normal is my normal playback profile.

    There used to be several playback profiles, but now there are only about 5, 3 of which are VDPAU. CPU++, CPU--, etc no longer exist.
