Selected Test Results (selected in 'Test Results' table below)
Pretty much everything when used with a file or with an HDHomeRun.
What does not
Bringing up a video bitrate chart (paid version only) gives a black background instead of a white one. Attempting to take an HTML Export (all versions), the focus doesn't default to the "file name" field as it does natively in Windows.
What was not tested
A lot of the specialized functionality that I don't use. Using TSReader with a USB-attached tuner.
