No. If you want it to be a standard signal, it *MUST* have 525
lines. You could reduce the number of visible lines and leave the 525
alone. Trouble with that is now you're software-compressing the video,
since you'd be running 720x400 or something.
The proper solution would be to adjust the TV so it doesn't
overscan as much. Notice I didn't say *easy* solution... just the proper
one.

If you make a correct one, it should work. Sync polarity should
be observed as per the standard. If not, take the TV/transcoder back and
get one that isn't broken.
Oh, and if you actually find somewhere that actually *has* the
standards listed, do share. I haven't been able to find it... :)
