Today I had a lot of free time, which I put into a real NTSC TV
emulation. This solves the stripes, but is too extensive to be fitted
onto the card. I think I'm going to add an expansion connector to
allow for a real TV emulation.
The old "method 1" is still available! It will always be enabled in
LORES and it can be enabled in (D)HIRES. I'm still wondering whether I
should set "stripes" or "no stripes" as default. I actually prefer
"stripes", but others may not. POKE 49395,0 is all you need to select
the "method 1" and this setting will be kept forever until you turn
your apple off.

BTW: Converting to component video is for chroma bandwidth limiting is
unnecessary, plain caps between the R,G,B lines will also do it.
