To any of you Nero guys reading this forum would Nero ever consider supporting MP4 & MKV (H.264/ASP/AAC) files in Windows Vista Media Centre as it would be a great feature to have because the open source community don't seem to want to so there is a gap that could be filled by Nero in this area.
Haali's Media Splitter with ffdshow does work for playback of MP4 and MKV files in Vista & in media centre but thumbnails do not work* and the splitter causes other sorts of quirks in Vista media centre & Haali himself has said he has no plans to support Vista.
* You get black screens & the splitter causes Vista media centre longer to close than normal it seems along with bugs in thumbnails for other content as well.
I'm sure Nero would gain some customers & a lot of brownie points with the Windows media centre community if they did this
