external display & front row

hi guys,

I'm having a problem with front row... basically, when outputting to my external monitor (samsung 226BW), i use the remote to invoke front row, and it wont stay in that mode very long at all before the monitor stops recieveing a signal (at least, that is what i'm assuming is happening... my monitors VGA input is connected to my macbook, and the DVI input is connected to my PC... after a few seconds in front row the monitor flickers a bit then goes to the DVI input - which is the same response as if i'd unplugged the macbook video output)

to get back to the view i have to press menu on the remote and then press 'source' on the monitor to revert to VGA...

any ideas? ideally i'd like to be using DVI from my macbook but the PC only has DVI outputs so can't do it the other way round... not sure as that would help this issue anyway...

EDIT: p.s. the macbook is always plugged into AC while doing this, i can't seem to output to the external monitor when running from the battery for some reason...

 

hmm it seems to have fixed itself for now... has anyone else experienced this before?
