16:9 anamorphic : lower quality footage on my DV-cam ? - "Perry"

>I have Sony TRV900E. It can shoot DV in 16:9.
But some people say that the footage then is of a significantly lower
quality.
Because almost all DV camcorders do so by reducing the resolution of the
active image on their CCD image sensors. They reduce the size of the
image sensor by 25% then stretch that by 33% resulting in a
significantly degraded image.
Is this true ?
How can I best shoot with my DV-cam for playback on a widescreen 16:9
TV-set ?<
The horizontal stretching will be true of any camera source, and is done in
the analog circuits of the tv set by expanding the scanning, so there is no
artifacts involved.
The vertical stretching is done in all consumer DV cameras that offer proper
anamorphic wide screen mode (as opposed to letterbox mode) and does result
in artifacts due to the real time interpolation used. You will get better
quality by shooting in 4:3 and then stretching and cropping the image in
post, although this will need a lot of rendering time of course. After
Effects does a really good job, but EditDV PZR filter worked pretty good as
well.

I think you mean 5.02 Bruce!
Has anybody out there with Cleaner 5 on the Mac had much luck with producing
movies for Windows Media? Any tricks to make it more reliable?
