[streaming] Re: Streaming MPEG2 from Hauppauge PVR150 using VLC for Windows?

Wed Jun 15 16:05:59 CEST 2005

Ya, not as much as I wanted but I did a basic udp streaming form my pvr350
and as I remembered it worked fine without having to transcode anything, I
chose a format in the pvr driver properties via the dshow pane, the drivers
let u chose amongst mpeg ps, mpeg ts dvd, svcd and vcd. Which all work
pretty well, I use mpeg 2 ps, which is then encapsulated in mpeg 2 ts by
vlc, and I do not touch any transcode options, the cpu load while streaming
this is below 6% on my athlon 3200. It might very well be the drivers for
the 150 are different, although as far as I can see form some snooping
around on the Hauppauge site they seam to use same drivers for 150,250,350
and 500?
