the problem is that i capture the video to hdd with ulead video studio 6 in dv format,until here everithing fine but then i encode with tmpeg(the last) and i set to high quality dvd (to burn on dvd+rw)and i burn with sonic my dvd,everything ok,the problem is that the image only plays good on power dvd because when i put it on my dvd (yukai)and in a 51cm sony tv the image when is in motion shows a lot of pixels!what do you think is the problem !is it the software or my defenitions??
