Andrew, just trying to keep up with you but not really able to.  Just some feedback and a question.

With the fake-interlaced=1, a "real" interlace media file came out progressive too, so besides your bluray.m2ts, gg created bluray_tff.m2ts and bluray_bff.m2ts and made changes to bdcreate.C to pick that one based on ILACE.  I have yet to have him look into the bdcreate.C changes you tested but hopefully I can do so today will still testing more bluray media on the TV.

BUT, BIG QUESTION here and I already re-read the x264 url on deprecation of x264opts to be replaced by x264-params.  I can not get x264-params to work with tff or bff added at the end of the statement.  I even tried tff=1 and still does not work.  The only way I can get the interlace options to work is with x264opts.  So the question I have for you is, in your bluray.m2ts, can you verify that the vbv-maxrate=40000:vbv-bufsize=30000 actually take effect? I notice that you have them commented in the main section and added them to the end of the x264opts.  Thanks, Phyllis
