Divx -> DVD (filters to improve quality)

[cd090580]

Hi,
I've an old concert ripped from TV in Divx format (512*288).

the quality is quite good but I'd like to know if I apply some avisynth filter I can slightly improve (I know I won't get a very good quality) the picture quality.

I look for filters that don't slow down the process too much (without any filters it takes me +/- 12 hours to convert my 100 minutes video).

PS: I need filters that don't require SSE to run.

What filters you recommend me ?

Thanks a lot.

It's not worth your time. They won't improve the picture quality enough to justify the time spent.
