I did some more experiments. My TV can actually play all recordings directly through DLNA without any judder (it has other problems, though).
I also realized that both HD and SD recordings judder - but HD just not as strongly, but maybe more frequently. So I now suspect that this must be related with the network connection on the client side. I'll check cables tonight, but this experiment doesn't seem very promising.

Any thoughts, experience, hints, ideas on how to debug this problem are highly welcome.
