Canon 50D wont fire Inon strobes in liveview?

Ikelite ones work. Inons fire fine in normal view.

Is there a setting Im missing or is this a known issue, or is my camera 'special'? Any help appreciated

Edit: Using Ikelite housing, 40D upgraded to 50D.

Tracked down an answer for this:

40D wont fire non Canon strobes in live view.

50D will fire non Canon strobes in live view - as long as 'Silent mode' for live view is disabled.

Ikelite strobes will work as they emulate Canon flashes, and of course optically fired strobes will work as they use the camera's own flash to fire rather than an electrical link.

Bit obscure but may help someone else in the future.
