Settings in Make Video with Studio DC10

[Massa]

Hi,

After cpaturing with dc10 , 306x480 VHS, I edited the video and now I have to make an AVI to use TMPGENC after.
My doubt is, what codec and setting should I use for better make a SVCD after?
I tried the Indeo 5 with 480x480 but the results were worse than wiht 360x240. Why????
Actually the only acceptable quality I got was with 360x240 with any codec. It seems that higher resolutions takes to lower quality.
Please , help

Well, let me make the question more simple.
I don't understand why rendering at 360x240 brings betters AVIs than 480x480.
Could it be something related to media player? Or the Studio?
Interlacing?
Please, if anyone kwow something about, helo me
