Hello: <br><br>I recently purchased a Hauppauge PVR-1600, which I intend to use in a MythTV setup as an analog capture card, connected to "cable out" on my cable STB. Despite my best efforts, all I am able to see from the card's analog input is static, both in MythTV and reading /dev/video0 with mplayer. the clear QAM half of the card works fine -- it grabs all the clear digital channels my provider has to offer. <br>
<br>I am running Mythbuntu 10.04; here's what uname -a has to say: "Linux myth 2.6.32-22-generic #35-Ubuntu SMP Tue Jun 1 14:17:36 UTC 2010 i686 GNU/Linux". I'm using the latest version of the V4L drivers, which I downloaded yesterday from <a href="http://linuxtv.org/hg/v4l-dvb/" target="_blank">http://linuxtv.org/hg/v4l-dvb/</a>, built, and installed. And the cable is plugged into the correct input on the PVR 1600 (the top one). <br>
<br>Absolutely nothing happens when I change channels regardless of whether
it's on the STB, or using ivtv-tune, and regardless of frequency table I
use in ivtv-tune -- the static pattern shows no sign that anything has just happened, almost as if the tuner isn't doing any tuning. <br><br>I have confirmed that the STB's cable out is working, using a PVR 150. <br>
<br>I noticed the following in the output of dmesg -- note the triple-asterisk'd lines: <br><br>[ 27.136529] tveeprom 1-0050: Hauppauge model 74041, rev C6G8, serial# 7155635<br>[ 27.136534] tveeprom 1-0050: MAC address is 00:0d:fe:6d:2f:b3<br>
