Hi,
I know that some of you fine folks have built mythtv PVR's, so I'd like to
detail my own humble endeavor in these waters.
My system:
An old Compaq Deskpro (P-III) with 256 Mb RAM
Stuffed a Seagate Barracuda 7200 rpm 120 gig hd in there
Tuner is the Hauppauge PVR-350 with the tv-out piped to my tv
Well, I downloaded knoppmyth and installed in in there. I compiled the ivtv
driver (version 0.3.3) and the ivtv-framebuffer and X11 drivers for the
tv-out and compiled lirc for the hauppauge silver remote. The hardware
decoding in the pvr 350 more then makes up for the crappy cpu and I get
excellent video off of the tv-out. The only beef was that since I had only 1
tuner, I couldn'tplayback live tv and record at the same time.
So I got another tuner. The Hauppauge pvr150MCE. This puppy also has hardware
decoding so there shuld be no problems. I added a line
in /etc/mythtv/modules/ivtv for this tuner and rebooted. It loaded up fine,
and the device files are there (/dev/video0 for the 350, /dev/video1 for the
150). I ram mplayer on them (mplayer /dev/video0 and mplayer /dev/video1) and
got television playback from both.
In mythtv, however, the story was different. I fired up mythtv-setup and, in
"Capture Cards" I added the second tuner ("MPEG Encoder, /dev/video1, tuner
0") below the config for the first (pvr350, which was "MPEG
Encoder, /dev/video0, tuner0"). and linked my datadirect subscription to the
tuner0 on /dev/video1 in the "Input Connections" section. I then went to
"General" and "Host-Specific Backend" and configged "Maximum simultaneous
jobs in backend" to 2.
Now, whenever I try to play live tv in mythtv, it's a slideshow. Picture and
sound are impossibly skippy and slow. WTF, I say to myself and check on
mplayer. Works fine there for both tuners! so now I'm confused and dunno how
to fix this problem. I'd sure appreciate some advice from the gurus in
mythtvland who peruse this fine forum. I have some config details below:
Thanks for your attention.
