Subtitles:
Easiest way is to extract ONLY the subtitle you need into the same directory
as the .avi file and rename to match the .avi name exactly..
ie:

Dr.Strangelove.1964.40th.SE.WS.Eng.592x352.25fps.976kbs.96mp3.MultiSub.WunSeeDee.chinese.sub
Dr.Strangelove.1964.40th.SE.WS.Eng.592x352.25fps.976kbs.96mp3.MultiSub.WunSeeDee.chinese.idx

rename to

Dr.Strangelove.1964.40th.SE.WS.Eng.592x352.25fps.976kbs.96mp3.MultiSub.WunSeeDee.sub
Dr.Strangelove.1964.40th.SE.WS.Eng.592x352.25fps.976kbs.96mp3.MultiSub.WunSeeDee.idx


      OR


Dr.Strangelove.1964.40th.SE.WS.Eng.592x352.25fps.976kbs.96mp3.MultiSub.WunSeeDee.danish.srt

rename to
 
Dr.Strangelove.1964.40th.SE.WS.Eng.592x352.25fps.976kbs.96mp3.MultiSub.WunSeeDee.srt


Then play the avi and any player should see them.

If not, then install this
