@jdobbs;
I can confirm on my end that BD-RBV03703 corrects the IVTC/DECOMB problem on mpeg2 files that could make the audio go out of sync.
I see the avs created reflects (Telecide(order=1) Decimate() ).
Suprising to me is that the visual quality is improved noticeably on what is a pretty low quality original, and is better than just keeping it interlaced or using Decomb to deinterlace it. ( pending the original source! )
So congrats and thank you for such a quick find and fix.
