Hehe, just my thoughts - with so many files they just HAVE to be in there! :D

None of the files seem to be corrupted, there's 4 videos in each of them. Though it seems one of them is in there twice and one of them is a WMV despite being in one of the MP4 files.

Doh, and I just realized I only downloaded the MP4 files - maybe the "Light Master" videos are WMV-only... I'll report back after I broke the Rendo servers and my ISP by downloading the WMV file! ;)
