In vnsiserver, ac3 spdif sound seems all mixed up.  ATSC here only uses
AC-3, but 5.1 sound only plays with Left and Right front speakers, so I
can't hear any dialogue.  On my HD-PVR, I get no sound at all, xbmc sees
an AC-3 stream, but the info page says 0 speakers?  However, the audio
settings while the stream is playing believes it to be a 5.1 audio track
(which it is..)

vnsiserver seems much better with the hdpvr as it doesn't start and stop
the stream three times like streamdev does..  (Big blue light flashes on
the hd-pvr box when it's being used.)

Streamdev will not display output correctly from my pvr500 card using
pvrinput.  It works with vnsi and obviously vdr-sxfe..


Well, on the other hand, streamdev works with eac3 not vnsserver. In 
france HD TV use eac3 for audio.


Sreamdev works thus better than vnsiserver for me .


I suspect the issue we're having with vnsi is pretty much the same, 
audio passthrough is broken.  If vnsi recognises the audio then it 
converts it to only two channels.  In your case it doesn't so you 
probably get only a picture, which I get with my pvr-input based hdpvr.
My other issue is only with the pvr-input plugin and streamdev.  The 
analogue channels (which I use for cable channels through a set top box 
and a channel change script) gets scrambled when it arrives at xbmc.  
Ffmpeg doesn't recognise the codec.  However that works with vnsi.  My 
hdpvr basically does the same thing for HD channels.  It converts them 
to an h264 channel with ac3 audio.  With streamdev, it seems the input 
is opened three times before the stream is sent (Big blue light comes on 
and goes off three times) then 1 in 3 times 10 seconds later xbmc starts 
to show it.  With vnsi, within 3 seconds the picture comes on the 
screen, but no audio.


vdr-sxfe, the audio goes out of sync within about 10 mins with vdpau and 
the hd-pvr..

Yes I have video only, but because it doesn't handle well the audio, it 
probably consumme a hell of CPU and the HD video stream skips and has 
macro blockand then finally freeze. I had the same behavior with 
streamdev before applying a one line patch for eac3.

I use analog audio out when running directly on the hdpc (hdmi 
passthrough to be precise) eac3- pcm stereo (xbmc) - analog audio


However, I use a heavilly patched vdr 1.7.14 (for eac3 one single line 
but a lot of other things for packaged by vdr package maintainer) and 
streamdev (one single line for eac3 plus a lot of patches packaged by 
package maintainer).
