<br><font size=2 face="sans-serif">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.</font>

PVR-250 difficulties</font></table>

<br><font size=2><tt>I am a Newbie to Linux. I am currently running
the default install of<br>
Mandrake 9.1. I installed mythtv from the HOWTO as well as the PVR-250
as<br>
detailed in the "example configurations". My setup uses
a celeron P4<br>
1.8GHz, 384Mb PC2100 RAM, and ASUS P4VP-MX motherboard (I am using all
the<br>
onboard VIA devices: video, sound, ethernet). The Hauppauge card
I am using<br>
is a PVR-250 model 980 NTSC/NTSC-J. I am experiencing two difficulties
with<br>
watching TV.<br>
<br>
1) The first time I start mythfrontend after a reboot everything works
ok.<br>
However, if I stop watching tv and then attempt to watch tv again the signal<br>
becomes choppy and eventually locks up. If I switch over to the terminal<br>
window in which I started mythfrontend I see the message "prebuffering<br>
pause" then "waited 2 seconds for data to become available, waiting<br>
again..". The only way to regain use of the tuner is to reboot
the<br>
computer. I tried stopping the ivtv module (and all its dependencies)
and<br>
restarting it again without rebooting the computer, but that had no effect.<br>
I also updated the firmware to the recommended version from the ivtv site<br>
(from file pvr_1.18.21.22168_inf.zip), this had no effect.<br>
<br>
2) When I watch TV all I receive is static. I tried fine tuning the<br>
frequency with no success. How are the frequencies set? I use
DataDirect<br>
to set the channel info, but maybe I missed a step that sets the channel<br>
frequencies.<br>
<br>
I would appreciate any help on these topics<br>
<br>
Thanks,<br>
<br>
Dan<br>
