I'm transfering divx HQ dvd rips to svcd and keep geting the following problems.
I get several effects when creating (s)vcd, i get what i belive is called mosquito noise around objects, i get a strange mergeing of colors mainly around faces.
i also get something else i do not know what to call it looks like when u get a hq video clip a make it full screen ie zoom in on it looks like a blocky semi transparent layer that appears over the video.

For the mosquito type noise play with the Image Quality Priority setting. You are already at 20, but try 23-25.

For the other problem. Do you see this in the final mpg off the HD as well or just on the burned disc?

Keep in mind that even a Hi quality Divx is still a compressed copy of another compressed copy. So by making a SVCD out of a Divx from a DVD you are doing the third compression and it's going to loose quality no matter what. It will not look as good as a direct DVD rip.

I have yet to be able to make any AVI conversion anywhere near as good as what I could from a DVD. Even when the AVI looks great on my computer. I have been playing with bitrates and filters for weeks and can only slightly improve the quality on my TV. Background blockyness seems to be the biggest issue. I just ignore it now when I watch it on my TV. I don't claim to be any kind of AVI expert, but this is from my own extensive testing.

One thing I noticed right off is you should raise that Min to at least 300. Many DVD players have issues with very low bitrates.
