Haven't figured this one out yet. I'm running KnoppMyth R5A16 on an Athlon 2100+ w/ 512mb RAM, Leadtek K7NCR18D Nforce2 mobo and some old nvidia card.

Everything works great, except for the tuner card! All I can get is a green screen with a wee bit of static on the top. The tuner is a Vstream VS-TV878RF bttv card. The chipset is a Conexant Fusion 878A. I know it's not a hardware encoder card....

Can anyone help out at all? I was talking to cesman on the IRC chan and for the time we worked on it, could not figure it out. THanks,

linuxvirgin

sounds like the symptoms you get on cards that aren't bttv, but use the cxx??? driver.

I get the same symptom on my bttv card when it is either not tuned, or the antenna is unplugged. Does the output of dmesg indicate that your card is being detected properly? If not, you will need to pass a card= (and possibly tuner= parameter to the bttv module. There is heaps of info on the forum about how do do this. Make sure that you can receive tv signals using xawtv (after setting the correct frequency table an changing to a valid channle) befor trying to get mythtv working because setting up the channels correctly for myth is not trivial.

xawtv does not work. Linux is picking it up as a brooktree corporation bt878.

I'm not really sure what all cesman had me doing the other night...

Here's what I see in dmesg:

it's not detecting your card properly. I would check CARDLIST or google for your card to see if you can find out what card and tuner settings bttv needs.

I'm trying to find settings for this thing, but google isn't turning up anything. Last time I go cheap, I guess...

Where is cardlist? I found a thread with the patch, but it's not valid on my load of R5A16...

well it's in the kernel source if you unpack it, or google should be able to locate a copy of it for you.

I found the list on Google.... My specific card is not listed on it. cesman claims he got his working... how can it work if it's not on the list? Is there something more generic that I should try?

If cesman cliamed to get one of these cards working I'm sure that he posted what card and tuner type he used, but the only card I remember cesman talking about was a kworld card.

Yes, this is a Kworld card... I'm told V-stream is their tuner line. It all gets picked up as a Brooktree BT878. When I purchased the card from newegg, it was sold as a Kworld brand, it arrived as V-stream.

anyway, I'll mess around w/ it some more tonight when I have time to sit down and do some serious searches. Thanks for your help Xsecrets.

well I believe that kword is listed in the cardlist, and I know that cesman put specifics about the card and tuner type used. Also at least one other user has a thread with the information in it. I would search the forums for kworld. the posts will be rather old now, but should get you the relevant information.

Fixed. Used the settings from http://www.mysettopbox.tv/phpBB2/viewto ... ght=kworld

and it works just fine and dandy in xawtv.

NOW... my problem is, when I try to get into myth, and watch live tv, I get the last station I tuned into in xawtv, and if I try to change the channels, the video feed stops, the backend crashes, and I get thrown back to the mythtv menu screen. However, the audio on that channel continues to play until I either restart, or open xawtv back up and tune into a different channel.

I set up some programs to record last night, so when I get home from work, I'll find out whether it was able to change channels to do the recordings. Then again, I think the power flickered a few times last night (or at least, I heard my ups flipping out at around 4:30), so the machine may not even be on anymore .

you don't have your sound setup right. you need to mute linein and set it as capture. That's the sound problem, but as for not changing channels are you using ota cable sat are you using zap2it if cable have you tried us-cable and us-cable-hrc? (if you are in the US)

Not sure what you're saying about the sound. My onboard soundcard on the mobo doesn't work because the drivers aren't loaded. I had my line plugged directly into the back of the tuner.

I'm using zap2it for the station listings, and it has the correct provider in there for me. I'm using us-cable, which is what worked in xawtv. I haven't tried us-cable-hrc in Myth, but it didn't work in xawtv, so I'm guessing it wouldn't work in myth either. Again, I'll have to see if it managed to change channels and record anything last night.

I seem to remember seeing a thread somewhere (or maybe something in the myth mailing list?) about someone having the livetv problem... but now I can't find it!
