So what happens with guvcview ?

It just doesn’t open I’ve tried un-installing and re-installing

and does running it from the terminal give any cues ?

I don’t know, I’m at work at the moment but I’ll try that and report back

Many thanks

I haven’t really had a close look … but it looks like bluetooth might be causing an issue, can you remove the bluetooth device, reboot, and try again.

Also, make sre you’ve tuned in the video with xawtv first.

[EDIT]

If that helps … you might also want to try cheese without the bluetooth device connected.
