We have a 42PFL4606 and watch digital TV via CI+ (Ziggo, in the Netherlands).

What strikes me are the incredible lipsync issues this TV has. It's about 0.5 - 1 second it seems and there's no way you can correct this. Multi-channel or PCM mode don't seem to matter. It's both with internal and external speakers (via HDMI ARC). The delay setting hidden in the menus don't help as well.

Some other ppl seen this as well ?
