Thank you, Jaitea!
In other news, I've belatedly realized the analog to HDMI converter I use on the flat panel in the living room is adding it's own video gremlins to what I'm seeing. (The analog video inputs on this tv are screwy, but I didn't start using them until it was out of warranty.) Therefore, I'm going ahead with a 704 capture and will see how it looks on the other screen in the house before counting it out.
I know it would make sense to simply have everything in the same room on the better tv, but there just isn't space anymore. And I need to get to the back of the LD players, S-VHS VCR, and DVD recorder to swap cables around often.
And msycamore, I didn't intentionally plan to have three LD players, honest! ;)
