So, you mean add the & to the tail of the externalcommand MySQL field?

When I do this, I can get into watch TV, but I can't change channels as
it seems that commands are being sent to the script as follows:

/path/to/script & <channel>

The channel is seen as a second, unrecognizable command.

Can you elaborate a little bit on what you meant here?

Thanks in advance!
