NDSL is capable of playing movies with the homebrew applications developed for different types of clip formats. One of them is DPG, which is for MoonShell. Think back in previous time when I wanted to convert clips format to of different types, I used Super Convertor; it can transform among most of the common types, and most importantly, it is a freeware :) See their official website here.
However I find that the software (v2008.build.30 (Mar 22, 2008)) does not support Vista Home Premium at all. It turned my pc into a bluescreen with lots of words, and before I finished reading the first line, it reboot itself automatically. Perhaps anyone of you could share more information on this.
Since my current objective is to convert to MoonShell compatible clip format, someone actually recommended BatchDPG, a simple yet good tool for the only one type of transcoding.
To use the software, you need to install AviSynth and MS .NET 1.1 prior to the installation of BatchDPG. You can find all the links in their website here.
