I rarely watch the actual DV files, other than the time it takes to edit
the video in Kino. Most all the time I watch the recorded stuff on my 42
Plasma, via the Phillips 724 DVD player, connected to the component
input of the Plasma. I usually watch with Progressive Scan turned OFF!
too (long story). I can tell the difference on there without really
trying too hard. Even on my crappy bedroom TV, using a Pioneer 440
player, I can see the difference. Finally, on a computer screen with
mplayer I can see a difference too.

I do have trouble telling the difference between DV->MPEG2 and broadcast
though. When I say it looks as good as the original signal, I'm not
kidding. Of course if you watch long enough you will eventually see some
MPEG cruft that will give it away as being a recording.

Also, I did try using the denoiser a few months back. Actually encoded
and burned to DVD a whole bunch of video that was run through the
denoiser. We stopped using it because we all agreed that the denoiser
made the video look WORSE. Probably not the case with mjpeg video, but
that is my experience with DV.

I hesitate to call *anything* perfect, but for my money, the Canopus,
dvgrab, kino and mjpegtools is it for me.
