If the converted file that is created by M²Convert for ZEN plays fine (not freeze) on Windows Media Player (WMP), then you should be able to play it fine on your ZEN as well.
However, we did face a similar problem with a few other customers, but the video created by M²Convert froze too when played on WMP. This behavior happened when trying to convert long movies, and it seems to happen when the screen saver starts. Disabling the screen saver when converting with M²Convert seems to solve their problem.
I recommend you try this too on your computer (disabling screen saver while converting) and see if it solves your problem.
If the file plays fine on WMP (does not freeze) then this means that the conversion is successful, and probably there is an issue with the ZEN player itself.
To know for sure, try to play a really long movie from any source other than our M²Convert. Does it play all the way to the end on your device?
