Good news from my side: For me, the new MPFileWriter.ax fixes the problem under XP64! The latest SVN and MPFileWriter.ax still works under XP32 (expected that) and TV-Server seems to run under XP64 again (but only with the new filter). Hauppauge drivers are 2.0.48.24227 (CD 2.7A) btw. So it is my turn to send a big THX to ronilse!
