Please provide some information about the hard- and software used.

Box type: DM600C

I have both RF out and scart connected to my TV so I can watch both analog and digital channels on the TV. Problem is that when the box is in standby I get audio but no video on the TV if I force the TV to RF. The TV does not go to RF automatically if I put the box in standby (I think it should). I have no problem with RF out when the box is off or on. The problem only occur when the box is in standby. If I unplug the scart, the problem goes away. I think the box must be sending something on the scart in standby mode that confuse my TV.

Is this a known problem? Is there a solution ?

Thank you very much for the response!
It is good to know that it is a known problem, and not a problem with my hardware or setup. However, your link to the solution DOES NOT WORK. Please, fix the link!

The link works now. I ran the page through babelfish, and I think I get the basic idea. Thanks again.
