Fry's is running a special on the kworld 115 for $30 after rebate. I've reading that this card is basically the same as the 110 but I cannot get it to work on my R5D1 system. I already have a PVR-250 and an airstar 5500 installed. I followed the instructions at http://www.mythtv.org/wiki/index.php/Kworld_ATSC_110 (although I didn't do anything on the firmware since R5D1 has kworld firmware on the distribution). When I do a "dmesg | grep -i saa7133" I see


So the fact that I see it as a generic device is not good, but I'm not sure how to resolve this. I tried configuring in mythsetup anyway, but no luck. I tried configuring it as a "DVB DTV capture card", but the only DVB card # I have that is recognize is for the airstar 5500. I also tried configuring it as a "pcHDTV DVT capture card", but when I run myth, it complains that it can't lock onto any signal.

Any assistance that anyone can provide would be appreciated....

I was able to get my 110 running with the instructions from thread. I don't remember what I did, but it was worked ever since.

I tried several of the suggestions in that thread -- no luck. Perhaps the most interesting thing is that when i try "modprobe -r saa7134", I get an immediate kernel panic and everything shuts down.

I've made some progress. I had an R5D1 install hanging around on an old p3-500 system. I added this kworld 115 tuner to the machine and reproduced the problem of the system not identifying the card properly or loading firmware. I then did the following:

1. Added the following lines to /etc/modprobe.conf
2. Then I did the following:

Things now record properly with this card. I am guessing that the kworld 115 isn't yet recognized automatically and the modprobe.conf changes force it to be recognized.

Next step is to try this on my production machine to see if it will coexist with the other 2 cards I already have installed there.

OK -- I've confirmed that what I posted in my prevous messages makes it so that the kworld 115 card works. The key is forcing it to look like the kworld 110. I am now having a different problem -- this change is causing problems with my Hauppauge PVR-250 remote, but given that this is really a new issue that applies to more than just this scenario, I've opened a new thread at http://mysettopbox.tv/phpBB2/viewtopic. ... 8219#88219 to work on this problem.

Edit: Remote problem is solved -- see the thread reference at the bottom of the previous paragraph.

Glad to see you got it going. Might be good to wiki the setup proceedures so others can follow suit.

Actually, there's already a mythtv wiki article on how to properly install the Kworld 110. I've added the extra step required for the Kworld 115 to that article.

A quick follow-up. Just for grins I tried to use the analogue tuner that this card has. Here are my observations, for those wondering:

1. The card is not capable to tuning in both an analouge and digital transmission simultaneously. I read somewhere that this may be a driver limitation -- don't know for sure.

2. Video quality of analogue capture is not as good as my Hauppauge PVR-250 analogue capture.

3a. CPU utilization to record with RTJPEG codec was modest at quality level of 177 --- probably not more than 8% of a 3ghz core, but the visual playback quality of the recording was at best "fair".

3b. CPU utilization to record with RTJPEG codec was higher at quality level of 235 -- around 25% of a 3.0 ghz core. Visual playback quality was noticably better, but not as good as my PVR-250.

4. Never got audio to work, but given the above observations, I wasn't motivated to figure it out.

It does a fine job as a digital tuner.

Marc

i haven't tried it (no use for analog here... i just use it for digital OTA), but for what it's worth, i think that the k-world cards require you to use the 1/8th inch analog audio out to the aux in of your soundcard. i think that's the only way to get audio out of them for the analog tuner. not that i'll ever use it, 'cause i only got it for a pretty good cheap digital tuner.
