Apparently my current PC
can play DVDs when I was told differently by the place that sold it to me!
Granted, it's for the Resident Evil Wiki article on the MP5 SMG (as the IMFDB article for this movie has one almost identical) to illustrate my argument there about the G36C-type sight rail, but it's nonetheless an achievement for me.
Now I'll have to look through my DVD case to see what movies I have that need screencaps here.
