[SOLVED] No "Custom Filters" in MythTV menu

Hello.

I am currently trying to make my MythTV frontend play HD videos smoothly and the MythTV wiki says that I should try adding "vdpaubuffersize=32" if I suffer from artifacts (which I am at my HD anime). According to the MythTV docs there should be an option called "Custom Filters" in Setup->TV Settings->Playback, but I cannot find any text field for filters there.

I am asking this question here, because I guess that the archlinux version of MythTV is somewhat special. A mythfrontend --version results in:

Please attach all output as a file in bug reports.

I am using the plugin "mythplugins-mythvideo" from pacman for playback of local videos.

Do you know if the option has moved somewhere else, where I have not found it yet? or I need to enable something?

Go to TV Settings > Playback, page 3. There should be a list of different playback profiles, one of which will be used depending on the size of the video. If you don't know which is which, just do this for all of them:
1) Click edit
2) Optionally fiddle with these settings
3) Click next
4) Fiddle with deinterlacers and custom filters
In my experience the artifacts are much better now than they were when VDPAU first came out. Are you using the most recent NVIDIA driver?

Thanks a lot, I would not have found it there… I often was in that menu but I did not pay attention that there is a "next" button even in the submenu.

Seemed to work, I do not see any artifacts anymore in my 720p videos (mkv) after having added vdpaubuffersize. With the new value the CPU also remains at about 5-10% (on one core) even at 1080i (Big Buck Bunny, H264). Elephants Dream still goes much higher, but still seems to play smoothly.

Nice, glad it works for you. My GPU got up to 116 degrees Celsius the other day watching a 1080i movie
