I use xy-VSfilter as my subtitle renderer (since MPC's ISR likes to break typesetting)I can't say anything smart about the question but ffdshow itself can render subtitles.
I noticed it had a subtitle filter. I'll give it a shot and report back.
UPDATE: That's got them showing up. Just need to see if the typesetting and general performance are ok.
UPDATE 2: Performance seems to be good, but typesetting on some videos gets pretty messed up. I'm happy to use this for now if I have to, but getting xy-VSfilter working would be the best solution. Thanks a lot for the tip though.
UPDATE 3: Through some tinkering I've managed to get it working. I think I pulled it off by putting DirectVobSub below the FFDshow raw decoder in MPC's filter list. Again thanks for the help.
