Genlock doesn't interlace?

[Iggy_Drougge]

Lately, I've been using my A1200 on a 1084 monitor using a really cheap old genlock, which works amazingly well for its apparent build quality (or lack thereof), but I've been encountering one problem:
Interlaced images come out non-interlaced, IOW with half the intended resolution. For my video work, this is no real problem, but it makes my workbench almost unusable.
What could make the genlock behave like this? Do certain genlock chips just not like interlace?

PAL and NTSC by their very nature work in interlace. It is also dependent at what screen resolution you are working in.

True, but the Amiga can further interlace that interlaced picture, which the genlock obviously doesn't like. =)

Oh, I've always wondered what that commodity was for. Now I'll find out. Thanks. =)

Leirbag:

The input source is my VTR, which I believe can't be forced into interlace. Still, it's funny. When I was using my A2301 in Japan, it would display an interlaced picture fine as long as there was a live source, either TV or videotape, but would turn out de-interlaced when overlayed on the video's menus. This time around, with my cheap bastard genlock, it will turn out that way regardless of the video source (haven't tried with another Amiga as the source, though).
