I upgraded nvdia drivers to the latest posted on nvidia's website 270.41.06 and now I can manually run the video files from the command line with xine -V vdpau fifo://. this works for both the pvr-150 and hdpvr files. Still a black screen in lmce with vdpau support on tho. There is no audio on the hdpvr file but i understand this to be a problem with the transport stream the hdpvr uses.
ok, I rebooted and all is well with the latest nvidia drivers. I got the roku box running with vdpau under lmce. Thanks for all your help. Still no audio with the hdpvr under videos but the picture looks great :-)
Hmm, looks like your issues are solved exclusively by the nvidia driver update! The 270 drivers were still in beta when I posted the updated libxine2, I'll look at updating the link to the latest stable.
I have audio on the hdpvr file you posted just fine.
How is your audio connected? Are you using analog, s/p-dif or hdmi?
Do you have dts/ac3 passthrough enabled if you are using spdif or hdmi?
