Default 6200TV with DVI->HDMI to HDTV

I have just got a HDTV Panasonic TH-42PZ800A and I want to know if there is a Standard for DVI and HDMI which would stop this working?
I'm using a Nvidia 6200 TC DVI output.
ie could there be a compatibility with a DVI output using an HDMI adapter to a HDTV?

Panasonic customer care are trying to tell me this is why my Video out doesn't work with HDMI port on TV.
But this doesn't make sense, are all DVI output compliant ?
ie should this just work out of the box like VGA does?

I don't really have any experience with HDMI, but from what I've read it should work as long as the DVI-HDMI adapter came with your graphics card.

If it did not and you bought it separately, then the design is probably different enough to stop it from working properly.

EDIT: This has some general info that might help:

actually its a cable but I assume that the cable is just connecting wires from one plug to another in a different format.
Note it works for the Front HDMI port so this proves the cable/adapter is good.

Any DVI port can be converted passively to HDMI without any problem. HDMI is electrically compatible with DVI except that HDMI ports will always support HDCP.

Ati's Radeon HD cards come with special adapters which support sending out sound and that part of it only works with their own DVI-HDMI adapters. The're two different types of ATI HDMI adapters depending on the generation of the card and they're not compatible with any type of ATI card. These cards came with a sound chip built into the GPU and the special adapters were most probably used for licensing (i.e. you could get it for less money without the adapter and add the adapter (thereby paying the license for the sound chip) later).

For the GF6200 you shouldn't have a problem with sending out video with a bog standard DVI-HDMI convertor.

I think the fact that my adapter cable works in the front HDMI , but not the rear to HDMI ports probably prove its a problem with the TV, and I've just heard someone if having an issue with a DVD player further proves this, so I'm now reasonably sure that this is not a compatibility issue.
