Description Mark Nauwelaerts 2008-04-13 12:51:07 UTC 
Currently, it is assumed that the values in palette info in VobSub private data represent YUV data, as is the case for corresponding DVD data.
However, Matroska specs defer/refer to VobSub's .idx file for the actual de facto specs, and it turns out VobSub produces those by converting to (a sort of buggy) RGB.
