No mine is fine. I think i introduced some unecessary confusion. There are two versions of the THX calibration. Some of them have 8 squares and some of them have just one. Is your Lion King one called Optimode or Optimser? I believe Optimser is the newer one which has 8 squares(like my PAL T2) and Optimode is the older one with one square(like my NTSC Toy Story). I think!?

OK the Optimode/Optimiser thing makes sense

For my piece of mind have you got/tried any of the NTSC THX optimiser tests as you only mention the T2 one

I've just put the optimode on the R1 Lion King disc and on my PC there are 8 clearly visible blocks (4 different shades) - The text also states "This test displays four distinct shades of white in eight boxes"

On my Aconda/Pio 565 pairing (and your setup too it appears) you just see 1 white block - which isn't right

It does appear to be only a problem with NTSC though (I wonder if it's to do with the internal Progressive Scan processing ?)

I've read some postings on this forum that the Loewe Aconda suffers from a white crush problem on it's RGB and component outputs. That would explain why the Optimode test for contrast is displayed as a single white box rather than several small boxes of differing shades.

One way to be sure is to try the same test using S-video, as the white crush problem only affects RGB and component.

Cheers.

I'm currently using the S-Video (via Scart) output - S-Video directly into the front port is exactly the same, so i'm not totally convinced

As I said previously. It's probably a combination of DVD player output voltage and TV input sensitivity

Sorry mate, only Optimiser disc i've got is the PAL T2(and that displays the 8 squares correctly). I've got NTSC Finding Nemo due within the next couple of weeks and i believe that has the THX Optimiser. Will check it out for you when i receive it.
