[mythtv-users] 2 problems, in plain text

[Peter Hocking]

I've just rebuilt my MythTV PC using Ubuntu 9.04 64 bit & MythTV, 
upgraded to the most recent version of the fixes branch with a Silicon 
Dust HD Homerun tuner. I'm experiencing 2 problems that may be related;

When I go to watch live TV, it tries to display, then says, "Error was 
encountered while displaying video" & then goes back to the menu. If I 
run the front end from a terminal window, I see this;

If I set it up to record a TV show, it appears to do this, but if I 
attempt to copy or open recording from a Windows PC accessing it via 
Mythweb, I get    "006_20090531110000.mpg is an empty file". Can anyone 
offer any insight into this & a possible solution?

TIA
