Hey Larry ,
Thanks for your reply.
After many hours of trouble-shooting , I think I have found the problem , at least in part.
When I now power on the DV79 , it starts up in DVI mode , not HDMi , I have no idea why.
I also have a Sony KDL-40XBR2 and the HDMI from the DV79 to the XBR work fine.
There is something in Samsung`s software , that is doing the archaic " trying to boot DVI first , and HDMI second " thing.
On rare occasions , I used to is this , but I have not seen it in several years , it was really only during the transition from the whole DVI to HDMI thing around 04~05.
If I can find a way into the Samsung`s software and disable the the DVI kernel, then I think all would be fine , however I am not as familiar with Samsung as I am with Sony.
LOL fairly old !! U want to talk antiques , my amp is the Yamaha DSP-A1 / G , now that is old ! , but it still works and sounds fine.
As for the Samsung having an SPDIF input , no it does not , output yes , input no. I don`t think I have ever heard of a tv with an optical input , maybe on of the older Sonys , they always had "cutting edge" stuff as well as tv known for there high audio output , and possible one of those may have had a digital in.
No all I need to do is be referred to a Samsung expert that can go into to the F8000`s software and correct it.
That is not going to be easy , chances are it is imbedded within the tv`s frame work , it may never be right.
Of course the other way is to hack the DV79 and disable the DVI there !
