HDMI Sync Problem with hardware decoding - any thoughts on why?
I've long had HDMI sync issues from several HTPCs that would cause my sony projector to shut off. I could reliably get the projector to shut off after 40-50 minutes of video playback. Tried several PC configurations, nvidia GPU, ATI, Intel - they all seemed to have the problem. Software I used included powerdvd, vlc, mpc-hc - all had the problem.
In talking to Sony they told me to get a sony blu-ray player - and sure enough for the past year that blu-ray player has not once shut the projector off. But it also can't play all the files I've got so I still use the HTPC - and live with the uncontrolled shutdown.
I recently made a change to PowerDVD and switched from Hardware decoding to Software decoding - and this has seemed to fix the problem - going on 20 hrs and no shut downs.
I was wondering if anyone was an HDMI/HDCP guru and might explain what may be different in hardware decoding vs the software decoder.
