Hello all, I keep getting this error: "failed to query the needed interfaces for DVD playback" on my media player of choice: MPC-HC. This happens with every DVD I try to play. They are all DVDs that I burned and they work on a DVD player perfectly. I havent found many answers online, but I did find many questions, some dating back 6+ years! Wow. I tried a suggestion on doom9 forums (windows-> run -> "regsvr32 qdvd.dll" and "regsvr32 quartz.dll") but to no avail. I am stumped. Intersting thing, I tried playing the DVDs in Windows Media Player. I get an error. Tried mplayer2, it froze up and crashed for some reason. Completely frustrated, I even downloaded VLC player (ew) and tried that. Whaddayouknow? It worked! So it cant be the DVDs or my computer.... Any suggestions and tips?
