2. Some of the advanced TV configuration settings are not sticking (for instance resolutions, color space)
Resolution at 640 x 240 never sticks in either "Video Capture Pin..." or "Video Preview Pin...". Next time you check it shows up as 640 x 480. You can just ignore it by clicking Cancel instead of OK. Furthermore, recording resolution is set in you recording profile, and changing it in the "Video Capture Pin..." does not really have a effect.
Color Space setting should stick. If it does not, it is a driver problem (the property pages found on "Advanced Properties" are all displayed by driver).
3. The video in time shift mode is upside down (it wasn't a few builds ago). There seems to be a switch to correct for that... but it's disabled
Matt may be able to fix that.
I also had some problems with the deinterlacing filter (which sometimes refuses to work), and luckily found that deletting the TV setting entries in the registry would allow me to reset everything.
Deinterlacing does not work with all Color Space settings. You have to experiment with it.
With MC 9.0.160, there is also a Reset button. Try use it instead of deleting registry key. It will reset most (if not all) parameters.
