Yikes. Long long time no post. Projects are coming to a close at work, so I sent in a new (and probably useless right now) Wine patch - it supports some of the new instructions on the Pentium Pro and later CPUs.
I must figure out how to get XingDVD to work on Wine - I get a window with no controls in it and when I click where Play should be it says it can't find the DVD. The LiViD stuff desyncs rather badly in the opposite direction now that I've upgraded from a 400 to an 866 :-)
