Nice to know. The Twinhan cards (the dst module) is a completely 
different card compared to other cards. So making it a reference point 
for any aspect cannot solve any issues.

BTW, if you use the new drivers from my repository at, 
http://thadathil.net:8000/cgi-bin/hgwebdir.cgi/v4l-algo-test
you will get faster tunings since the driver now tries to improve 
previous situations. There is a module parameter dst_algo. For the time 
being one needs to use dst_algo=0 (SW Algorithm) since the HW Algorithm 
is not stable for some people. Check it out, would be interesting to see 
how it fares.
