Can anyone post noise filtering results?

[ChannelK]

If anyone has done noise filtering tests using the light medium and heavy noise filters (via GKnot) on a noisy source, would it be possible to post some screen shots (before and after type thing)

(Thanks in advance)

and why can't you do these tests???

I tried but i cant find a DVD noisy enough for the difference between light and medium filtering to be noticable, that is, the outputs from both levels of noise filering on the dvd I tested on looked visualy the same. I have heard that gaussian noise can be added to a vob but have been unsuccesfull to do so in my attempts.
