[QUOTE="kszabo, post: 420721, member: 61646"] yes, something like that happens. I had AMD X2 BE-2400 first with this MoBo (128mb sideport videoRAM) which could not deliver nice 1080i picture (1080i was watchable though). After Upgrade to Phenom X3 the 1080i pic quality increased a lot. And the pic quality remaind the same (nice) if I deactivated the sideport vRAM in BIOS completely. This means 1080i playback needs more than 128MB RAM and the sideport solution does not increase 1080i deinterlacing quality.
