Although madshi does not plan to support "deinterlace" capability, I still would like to explain some rules to deal with the interlaced contents here.
For interlaced contents to be "vertically" scaled, it needs to be deinterlaced first no matter the output device is progressive-scan (most LCD, regular PDP) or interlaced-scan one (regular CRT, Hitachi ALIS PDP, special LCD monitor for broadcasting 1080i content inspection).
For interlaced-scan output device, it can be chosen to do the separate vertical field-scaling on interlaced contents to avoid the deinterlacing process. But the good motion-adaptive deinterlacing + frame scaling mode still produce better video quality, especially in the static scenes.
For progressive-scan output device, there is no choice. "deinterlacing" process must be done for interlaced contents before the horizontal + "required" vertical scaling processes.
