Okay. You wanna learn how to use gypplay. I tried to use the instructions and found out that the instructions were too vague. But here is what I know:
To convert the files, you have to use tmpeg or xingmpeg, but you computer must be extremely powerful to accomplish this.
And if you are having trouble burning your vcd, go to www.dcemulation.com and look for gypplay in the search engine. This is the set of directions that worked for me and continues to work for me until this day. In fact, I burn dragonball movies for dreamcast owners and "give" them the movies in exchange for a bright green bill that I am quite fond of (suckers...)
