SOLVED: Roku app crashes when showing thumbnails

[TheDreadPirate]

It varies depending on your Roku model. My Roku (4802X) direct plays MPEG2 without issue. I've also seen a bug with the Roku app where, depending on how hardware acceleration is setup, MPEG2 in TS will direct play if you have HWA enabled and it will fail when HWA is disabled.

Remuxing to MP4 should work around the issue, if you have the same issue as that github link.
