Videotext is reinserted into the blanking intervall, so it is well possible 
that there is nothing like that with S-Video.
Usually, if you set a PID to the MPEG decoder with the special teletext PES 
type set, it will automatically reinsert this one. If you request that PID 
for a cReceiver, it won't be reinserted by the firmware. So I am pretty sure 
that the firmware can only handle reinsertion from internal sources.
