I have an EX-88 which provides S-Video out on AV1. I now have an EX-98 (same+VHS), but find that although the manual says S-Video out is an option on AV1 it does not appear on the setup screen. The only options are Video, RGB1, and RGB2 - the S-Video option is not there (it is on the EX-88).

Anybody else have an EX-98 with this issue ?

Well according to page 76 of the manual I've just downloaded from Panasonic UK it should appear in the menu between "Video" and "RGB1"

Very odd. What does it say in your manual?

Exactly the same, although it's on Page 83. Which is exactly what the EX-88 also says. The Spec does say S-Video out on AV1 and S-Video in on AV2 (same as EX-88)

Seems the 22MB version of the manual is the one you have (I first downloaded the 5MB version)

Does seem very strange. But anyway I would use RGB as that should give you a better picture than S-Video. Unless you have a cheap and nasty telly that doesn't handle RGB too well (seem a few of those in my time). But any decent TV should give better results with RGB.

Still would be nice to know why S-Video isn't available.

Sometimes there aren't enough RGB enabled SCARTs on a TV to allow everything to connect at the best analogue quality.

I had the same issue updating a customer's set-up with a Freeview box yesterday. Potentially three RGB sources (Sky box, new Freeview box and a Home Cinema kit) but only two RGB enabled SCARTs. S-Video via SCART was the fall back on the third SCART input.
