[mythtv-users] Hauppauge PVR-250 difficulties

[Dan]

I installed the newest version of alsa 1.0.7, installed mythtv from CVS, and
set the pci latency to 0x40.  Now I get prompted with "CONTINUE WITHOUT
AUDIO!" every time I select "Watch TV" and I still get the ringbuffer error
message.

  I can only speak as to point 1.

  The prebuffering pauses are probably not due to the capture card but
rather to the audio device, or so mine were on a Pundit-R which also has an
asus mobo and uses the atiixp audio driver. The solution was to compile
mythtv from CVS and toggle the audio support from OSS to ALSA. I have had to
set the latency_delay for the pci cards as well.

  I am a Newbie to Linux.  I am currently running the default install of
  Mandrake 9.1.  I installed mythtv from the HOWTO as well as the PVR-250 as
  detailed in the "example configurations".  My setup uses a celeron P4
  1.8GHz, 384Mb PC2100 RAM, and ASUS P4VP-MX motherboard (I am using all the
  onboard VIA devices: video, sound, ethernet).  The Hauppauge card I am
using
  is a PVR-250 model 980 NTSC/NTSC-J.  I am experiencing two difficulties
with
  watching TV.

  1) The first time I start mythfrontend after a reboot everything works ok.
  However, if I stop watching tv and then attempt to watch tv again the
signal
  becomes choppy and eventually locks up.  If I switch over to the terminal
  window in which I started mythfrontend I see the message "prebuffering
  pause" then "waited 2 seconds for data to become available, waiting
  again..".  The only way to regain use of the tuner is to reboot the
  computer.  I tried stopping the ivtv module (and all its dependencies) and
  restarting it again without rebooting the computer, but that had no
effect.
  I also updated the firmware to the recommended version from the ivtv site
  (from file pvr_1.18.21.22168_inf.zip), this had no effect.

  2) When I watch TV all I receive is static.  I tried fine tuning the
  frequency with no success.  How are the frequencies set?  I use DataDirect
  to set the channel info, but maybe I missed a step that sets the channel
  frequencies.

  I would appreciate any help on these topics

  Thanks,

  Dan
