About video converters - a little need here...

[Alex KL-1]

I'm trying to find a HDMI to 480i component video converter/scaler, but this is not sooooo easy... almost all are HDMI to 480p or higher, and most even don't have scalers.
I have a notebook with S-Video with almost any interlaced format used in early 2000's in the world, but I want another device for not depending 100% of it, and another for a relative that have a old color TV and wants to use things like Chromecast on it (for fun).
Old color TV here is terrible to use this, because of the oddball PAL-M ("480i 60Hz PAL"). None of converters today have this format. All are NTSC or PAL that Europe used. With component or RGB, I can convert 480i RGB or de-matrixed component video to PAL-M using a IC, easily (I have one).
And thanks to PAL-M, I only have the mentioned notebook to watch old 4:3 programs in my old color TV's...

If people here have experience with those video scalers, I will very grateful with any tips!
