OK,
Given the fix for this in the 6.0.4 release, I wiped all my metadata and did a complete scan of the library to make sure all my 576p material was correctly tagged. First material I checked still shows a TV Show as 720p, even though the library resolution filter tags the material as SD. MediaInfo extract below. I will check all my DVD rips for the same later today. Am I missing something here?
