[mythtv-users] Kworld V-Stream XPert S-Video input howto

[Ben]

I have 3 Kworld V-Stream Xpert cards setup correctly for DVB-T input 
with MythTV. 
I would like to able to utilize the S-video inputs so I can hook up the 
VCR and switch between DVB / S-video.  Using the 'c' command in livetv 
only gives me the DVBinput.
However I cannot get  both the  DVBinput *AND* the S-video to work  
together.  When I add 3 V4L devices in Myth Setup (giving me a total of 
6 Input sources),  Live TV then picks up the S-video/ composite  input 
(I can switch between the two using 'c'), but now I cannot see the 
DVBinput.  Is there a way of switching between DVBinput and S-video 
directly using this card?
I've googled around but  and come up with a couple of references for 
what is happening:

Kworld cards DVB / S-video, but it doesn't quite explain how to be able 
to switch between the two in Myth:

channel input

Is the hack still necessary to get the S-video input to work? Is there 
now a more elegant solution, and if so could someone please the steps 
necessary so I can switch between DVB & S-video.

Cheers
