i think that was the same case on my first run with auto3d enabled...tried pretty much also 3dsbs to 3dtab directly and mvc.. all was working fse also until a playlist jump with short samples playlist. only the first was displayed correctly after files changed the second and following refused to display only myvideo osd reappearing with rates switched right (saw still mad stats^^)..from log:release madVR earlier but this lead to an exception because madVR is released while the Auto3D thread continue to do analysing.
