I ordered a Kworld software capture card from newegg after reading that a few follks had success in Myth. I searched here and found a post from cesman and tried these settings in /etc/mythtv/modules/bttv:


No luck. It appears that my card is detected and using the bttv setting:


I have put this card in a clean install of r4v5 and it is the only capture card in the box. This is the second box I have put together, it is exactly the same as my signature shows exept this Kworld capture card (no PVR 250)

Anyone had success with this card? Any suggestions?

Well, after many hours of tinkering, I had a little sucess. I decided to try R5a12 and see what happend. I did a fresh install of R5a12, got the nvidia drivers loaded, configured the xf86config-4 (I think). When I tried to watch tv in myth only got snow, could not change the channel.

Then I tried xawtv. It worked right away, better after I ran scantv and configured the settings. If I set xawtv to say channel 32, got out of xawtv,then started mythtv, I got a good picture but could not change the channel. I was on the channel I previously left in xawtv. In xawtv I could change the channel with the keyboard, all channels came in good and full screen looked good also. I had a week sound signal for awhile (only in Mythtv never sound in xawtv) , but later I got no sound. I have changed every setting in bttv to every thing I could find on google, but to no avail. The bttv setting above works the best, but cannot not really functional. About ready to throw in the towel on this capture card.

Hi I too as this card. I have spent many hours trying to get it to work and have not had much luck with it. I am wondering if you have any recent improvement or hints to help with the endevor.
Thanks

donjuan,

I have made some progress. I have the card working for live tv and recording. I used the settings I posted above in folder: /etc/mythtv/modules/bttv.

Turns out all my problems were related to me setting up the capture card in Mythtv-setup wrong. Once I had that right, and had the nvidia driver updated, the Kworld card began working. But the sound quality is not very good because of my onboard sound card. The sound directly out of the Kworld sounds good, but it sounds bad after going through my sound card. I am working on installing another soundcard right now. I hope this fixes sound for live tv and recordings.

If that works, then I am going to try and tackle the remote set up.

Well, I thought I would post my final results with this Kworld bttv card. I did get everything working satisfactorily in R4V5, including the remote.

I got the capture card working by editing /etc/mythtv/modules/bttv as shown at the top of this post. Then do the proper setup in mythtv-setup and you should be able to view live tv and record with no problems.

However, sound was a problem. My onboard sound card (sis 7012) did not work quite right for recording. Very poor sound. So I popped in a cmeida 8738 pci chipped sound card and had the very same poor results. A google search showed others had problems with the SIS onboard and the cmedia pci sound card. So I dug up an old ensoniq pci sound card, and the sound worked good. It was the line in on the sound cards that did not work correctly with the bttv capture card. I have a PVR 250 in another box with the SIS onboard sound and the sound is fine. The PVR 250 records sound directly to the HD and only plays on the analog out of the sound card, which works well.

Then for the remote. I just followed the LIRC HOWTO in the wiki:
http://knoppmythwiki.homelinux.org/inde ... =LIRCHowTo

I selected the Kworld card in the setup script for lirc-0.7.0pre4, then make, make install. Then I edited /etc/modutils/lirc and used lirc_gpio instead of the existing lirc_i2c (see wiki for more details). After running the setup script, there was a message about having to use lirc_gpio.

Then I untarred /usr/src/remotes.tar.bz2 , went into the new directory and copied the kworld.conf file to /etc/modutils. I backed up lirc.conf, then renamed the kworld.conf as lirc.conf.

At this point I rebooted and tried the remote. Some of the keys worked right away (like the numbers keys), others did not because I had not mapped them correctly yet. So on to mapping the remote keys.

The keys are mapped in /home/mythtv/.mythtv/lircrc. So I backed up the file lircrc as lircrc.hauppage, since I wanted to save the correct mapping for the hauppauge pvr 250 remote. Then I edited the lircrc file and renamed the keys I wanted to use as shown in /etc/modules/lirc.conf (the kworld one we previously installed). Pretty easy to do, just open up the /etc/modules/lirc.conf file in one xterm while you edit the lircrc in another.

A couple of final notes:

1. For some reason the ch+ and ch- keys on the remote did not seem to work while I was connected to a monitor, so I mapped a couple of other keys to do ch- and ch+. When I put the box onto a TV suddenly ch- and ch+ keys worked (I still had them mapped in the lircrc file). I have no explanation for this.

2. I did try to install the Kworld BTTV card and remote using R5A12. The capture card worked fine but I could never get the remote working. I kept getting an error about lirc_gpio not found. A google search showed that this was a problem for some others using the 2.6.xx Kernel. However, I am a very inexperienced Linux user, so others may be able to solve this problem, or I may have just totally blundered somewhere during the compile/install process.
