Hello, and thanks for answering.

[snip; output via Matrox G450]

...

Everything with 704x576 (and presumably 720x576) resolution works, but unfortunately some channels send other resolutions, such as 528x576.

528 I've not seen. 544 I have...

Yup. National Geographic seems to be fond of 544, Extreme Sports sends 528 at the moment. Neither one works.

Hmm? They all require scaling to 768×576 or 1024×576 (if the display mode in use has square pixels).

It doesn't, display mode is 720x576 - output is to CRT tube via S-video, and that particular resolution has been pretty much the only one I got working with G450 and DirectFB. If anyone has working configuration for that one, I'm all ears 8)

Install the -dbg package. Get a backtrace. You might also want to print (at least) local variables.

I'm pretty much a n00b when it comes to debugging linux programs, so I might not get all the info at once, please bear with me :P

Short log and backtrace:

Apparently there's no -dbg package available for xineliboutput-fbfe.

Or (possibly better) provide a short sample.

I guess that can be arranged. Just cutting a piece of vdr recording will suffice?

Either way, I think that the scaler configuration is also needed.

If I had an idea where to get it, I'd be happy to provide it. 8) config_xineliboutput has pretty much everything video related commented out, that is, using defaults.
