btiltman, good question which I will attempt to answer.
Some results do indeed show hours and minutes whilst most simply show minutes. This may be seen more often with different data providers or might be due to older reports. Anyway, there is a simple solution.
You can do a manual edit and rewrite the displayed time, e.g. for 61 (mins) enter
1hr 1 and 1hr 1 min will be displayed.
I don't think there is anything in TViXiE itself that will automatically convert minutes to hours and minutes but will ask for you.
I have held off tidying up my templates because I still hold some hope that mediainfo support will be officially integrated into TViXiE. Once that happens, I will be able to release a more meaningful update.
In the meantime, I hope my reply helps you
