An Oppo 93 and above will output 1080p24 from 720p24 mkv, however it won't output DTS-HD (just the core if you are lucky). However, if you convert the mkv to Bluray structure (as BDMV folder on USB drive or burned to Bluray disc) an Oppo 93 will play it back just fine in full resolution.
You are probably going to tell me next that you have an Oppo 83.
An Oppo 80, actually. But thanks anyways. I plan on building a new desktop PC eventually, so I guess I'll just make my own 1080p24 upscale. Although one made directly from Harmy's 720p24 master instead of the compressed encode would probably look better.
