I have downloaded the different samples on this great web on VCD/SVCD/XVCD formats and happily enough my DVD can play all of them!!

However, due to the limited time of the samples and because they are from different movies, it's difficult to compare between them in order to choose which format gives me the best quality vs. storage capacity. Also the samples held here are of dark scenes of films. So, here is the question:

Does anyone have samples( for the different VCD formats) from the same movie & scenes (preferably not dark scenes so quality difference can be easily noticed)?
