<br>I spent most of last night looking through the list archive and googling<br>but still can't make headway with my setup. If I missed something please<br>feel free to tell me to RTFM, as long as you point me to the FM.
<br><br>I'm setting up 0.18.2 on FC4 using an Nvidia 5200-based card and an<br>HD3000 with an OTA antenna. The system is an Athlon 1700+ with 512MB of<br>RAM and the latest FC4 kernel and nvidia drivers.<br><br>I followed Jarod's FC how-to and I have myth installed and configured but
<br>a couple of things are still wrong. After a reboot I have to manually<br>modprobe cx88-dvb then chmod /dev/dvb/adapter0/* so that the mythtv user<br>can read the video card. (The latest HD3000 firmware is being loaded.)
<br>Once I do that, if I tell myth that the card is a standard v4l it'll pull<br>in stations but the quality is far worse than with a TV hooked up to the<br>same line. It won't let me do a channel scan when set as a standard v4l
<br>card and the audio is often out of sync with the video.</blockquote><div><br><br>get the pchdtv-extra from <a href="http://pchdtv.com">pchdtv.com</a>. it modifies modprobe.conf and adds udev support.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
When I set the capture card type as dvb it'll do a channel scan and find<br>plenty of channels and they do come in very clearly, but they stutter a<br>lot even though the CPU load is only about .75 and there is at least 100MB
<br>of free RAM. But it doesn't find most of the standard channels that come<br>in (albeit fuzzy) in V4L. Also, the audio that comes through the HD3000<br>when in V4L mode isn't there in DVB mode. No TV audio comes out of the
<br>sound card, a chaintech 7.1, though Linux is able to use it just fine.<br>It's possible that myth is sending the audio to the S/PDIF port but I<br>haven't had a chance to check that yet.</blockquote><div><br>dvb is for digital tv, while v4l is for analog tv. i believe hd-3000 in v4l mode uses line-in for the audio. but in dvb mode, the audio should be embeded in the stream.
<br> <br>and it seems a lot of people are having problem with hd-3000 since the dvb driver was included in the kernel. it used to work fine for me when i had to compile the dvb driver for the 2.6.11 FC3 kernel.<br><br></div>
