The flickering is probably due to interlacing and is especially evident on thin lines in stills...there are some ways to reduce the effect (reduce interlace flicker etc..) but I haven't succeeded in eliminating the effect completely yet...
Where are you from btw? Your name sounds Catalan...right? I live in barcelona...
I'm trying to reduce the file resolution from 2048x1536 to 720x576 (more or less),
and the flickering is reduced obviously.
And yes I'm Catalan and live in Barcelona too.
