Sad! And nvidias bug report feedback == null.. Thanks for testing though!

This autosensing is not done by the FLI2300, but by Philips circuitry.

Normally, the FLI2300 are thought of as the best deinterlacer for stuff
like sports etc (video mateial) (vs SI).

So, what scaler/deinterlacer do you have on your proj? Silicon Image? They
both have their advantage, of course, but the HTPC is inferior on HD
material imho, espeically when the bitrate goes high. (over 20 mbit is not
nice on my HTCP, that´s for sure).

This is true, but as long as we do not have CPU´s powerful enougth,
hardware solutions will be better. Also, a big problem is that HTPC´s
cannot change their refreshrate to the framrate. Which means bad picture
quality, unless "burning" video bandwith by going over 85Hz refresh (or
prefferebly higher), but who wants that?
