Actually, surprisingly, it sometimes does work. I always thought that the fiberoptic output on HDTVs was solely for the internal ATSC tuner to pass Dolby Digital surround sound to an external receiver or processor. But some TVs do pass-through Dolby Digital sound from HDMI input devices to fiberoptic outputs.
The problem, of course, is how do you guarantee that the TV only be sent a Dolby Digital signal over HDMI? Most DVD players (including the BD35/BD55) do not have a mode which will always output DD, so if you have a DTS soundtrack or multi-channel PCM for that matter, what gets sent to the TV? And in the case of the BD35/BD55 there is some evidence (backed up by the documentation) to suggest that the player queries the TV via HDMI, determines that it is a 2-channel device, and automatically sends it two-channel PCM, regardless of the movie's soundtrack.
I agree that ultimately he's going to need to route audio to the receiver directly, instead of through the TV, but that may be a problem is he only has one or two digital inputs on his receiver. It would be a nifty feature of a TV to be able to pass the incoming digital audio signal coming in over HDMI (be that DD, DTS or PCM) and transparently pass that out either via an HDMI output, or a fiber optic output (given the limitations of the S/PDIF format, that is).
I think it would be too complicated to implement however.
