Unfortunately TMT5 is the only playback program that I have. Well, my BD drive did come with an OEM version of PDVD9, but the audio options are crippled in it, so I'm not sure how good of a test it would be. I tried the PDVD10 trial last summer and there were enough clunky things in its interface that I didn't go with it, and I don't think they'll give me another trial just for this test.
I did reconfirm my results with TMT5 tonight. With UAC disabled and the refresh rate set to 23, it slowly loses lip sync over several minutes; after about 20 minutes, it is notably off. Pausing or rewinding a little bit and then playing resyncs it, but then it slowly drifts from that point. I tried this both with it bitstreaming DTS-HDMA to my receiver and with TMT5 decoding to PCM, and the results were the same.
With UAC enabled and the refresh rate set to 23, lip sync stays locked on for the full movie while bitstreaming DTS-HDMA. But this has the dreaded 24.000 bug.
I would like for somebody else to confirm what I'm seeing/hearing, and I'm curious how PDVD10 behaves in the same test.
