Thanks gonk.

I also dug around looks like the Sony S370 and S570(maybe) support it as well, and I'm transcoding to h.264 video so that should be available on a Bluray player. I'm not playing files I download or anything so I have full control of the format.

I got the BDP-460 shortly (weeks I think) before the 370 was out, apparently, or I din't know it supported DLNA. Ah well, figures.
