I will have to try again, but the one time I tried to skip back a few seconds under XBMC 13.1 (Ubuntu 14.04 64-bit), the video hung. To get anything other than audio going again, I had to stop then resume the file playback. I'll try jumping around in it again later (pausing seemed to work fine, though).
Question for Harmy, what was the source for the opening crawl? I assume it just came straight from the BD; wherever it came from, it doesn't seem to me to be as sharp as the crawl you recreated for SW. More importantly, when text comes onto the screen at the bottom it has a bit of a yellow bleed around it, which goes away some the further onto the screen it crawls. Is that something you consider as having looked that way originally, or might a newly generated crawl be in order for v2.1?
