Wtv, dvr-ms anything?

I have the sony nsx and i thought i had the converted wtv to dvr-ms files playing but now i am getting no sound using the same Generic DLNA, they don't even play with other profiles.

Is there something that I should look at to get this to work again?
One dvr-ms has sound on the computer but not streamed.
2 dvr-ms have no sound on computer or streamed.
the wtv original has sound on computer but can't play it on tv.

or Is windows media center recording just not compatible?

ok i found out that some PBS channels do not have their audio in a format that will allow it to be passed through to a wtv to dvrms conversion.
but the channels that do have this and i get audio in dvrms on computer, the audio does not go through when streamed.

Any help for that?

converted wtv to mpeg2, all is well now.
