[mythtv-users] How to use 'Play Watch Recording' ?

[tuphan]

Hello all,

I just set up the Mythtv under my linux box, and I do not have the TV card
yet. I would like to watch a movie clip, for example,  test.mpg by using the
'Play Watch Recording' from the 'mythfrontend' but I do not know how.

The mysql and mythbackend is connect successfully. Would you please let me
know how to set up in order to play this movie clip. 

Thank you in advance,

Tony
