Ok so I have to use layers for optimal results - that I get. But I don't understand why the decoder would report frame errors when I try to blit the decoded frame.

Without knowing a little more about where your data is coming from, I couldn't say.  If you're trying to play something from a digital TV tuner and you can't keep up, that'll cause problems.  Alternatively, it could be an unrelated problem.

Also I just tried my first layer implementation ever - and I still get
the Frame errors - but no pictures at all.

Try some of the DirectFB test apps with the overlay layer and see if they work first.  You can get any app to display on the overlay by using the primary-layer option (see man directfbrc).

I might be a bit hung up on the wording in the README. Even though should use layers - I should still blit from mpegfb[x], right?

Yes.

I guess I can trust I have the right chip, no?

I've no idea.  Tell me what hardware you're using.  Of the VIA chips, only the CLE266 has the V1 overlay layer that you need to use the hardware decoder directly.  The later chips don't have this and require different functionality that is there in the hardware but not currently supported by the DirectFB unichrome driver.

uhm... I just read some of your earlier posts on the internet. They seem to rotate around TV output - I am not using tvout, that has nothing to do with the issue, right?

TV out is a separate issue.
