thanks.
I saw your guide and helped me a lot. eg yesterday i recorded a soccer game from TV, with 768x576 resolution (16:9) and i did the enconde with MeGUI and everything went very well. I noticed no loss of image quality was much better and without interlace lines.
today I will try to record a tv concert (Kaiser Chiefs RAR 2006) and make the enconding in XVID and then i will tell how it went.
once again thanks.
