AverTv Studio and myth

I am thinking about building a myth box. Right now I am running win2k and I
have a AverTV Studio card. It works ok but it crashes about once a day.

The only thing I use the computer for is as a tv, to show dvd's and play
console games.

I looked around on the mailing list archieve and I haven't found anything
about the AverTv Studio cards. Can I build a myth box around this card?

Thanks

Jack

RE: AverTv Studio and myth [In reply to]

Hi Jack,

I'm using a Aver TV studio card. I did have it running in myth under
redhat quite nicely but I had to put the project to one side for a
while. As I write this I'm compiliing Gentoo on the same box and will be
trying to get it working. I had a lot of problems with the card setup,
possibly because I'm in the UK and setting PAL input was quite tricky.
Also getting the remote to work was a nightmare but I did fix it
eventually. Bottom line it is possible and if you get stuck just ask I'm
sure we can get you going.

Adam

I've posted to the list numerous times about that very card. It's a
pile of crap. I have one. I use it as a secondary tuner, and it does
work, but the image quality isn't the greatest (but then my primary is
a PVR-250). It seems from what I've read that the primary problem
w/AVerMedia's cards is crap tuners, so they need very clean signals.
We'll see how my AVerMedia M179s work when they get here...

RE: AverTv Studio and myth [In reply to]

I've got to agree the tuning quality of these cards is a little weak.
But a good signal does help, and I mostly use mine for the composite
input which actually works very well. Being analogue you need that extra
cpu power which can cause quality to fall too, but I'm running an amd xp
2400 and it keeps up. I've never tried btaudio, has anyone else? Anyone
got it working and have some tips for it?

Yes, I'd expect less problems when using composite.

And I'm running a 2600, so lack of cpu power isn't a factor in the
crappiness of the picture (compared with my PVR-250).

Yes, posted that to the list some time ago also.

The bttv drivers can't ever find an msp34xx chip on mine. Nobody (on
either this list or the v4l list) seems to know if there was a revision
in the card that removed it, or how to manually inform the drivers
where it is. In short, I've never been able to do btaudio on mine. Some
people have said they can get it working, but the quality is mediocre
(analog only, digital definitely won't work), and there are assorted
issues getting the right audio channel (SAP often gets selected for
some reason).

fwiw, I posted a few weeks ago on the SAP issue with my avermedia card*. To close the loop on this, I now have the following params in modules.conf and this does seem to fix the SAP problem:
options bttv audiomux=0xff44e gbuffers=8

Part of the trouble in diagnosing the problem was that rmmod/insmod bttv didn't seem to be a reliable testing system. Rebooting was the only conclusive way of testing the configs. This doesn't really make sense...but whatever.

* this avermedia card as detected:
bttv0: detected: AVerMedia TVPhone98 [card=41], PCI subsystem ID is 1461:0003
bttv0: using: BT878(AVerMedia TVPhone 98) [card=41,autodetected]
bttv0: Avermedia eeprom[0x4803]: tuner=2 radio:yes remote control:yes

No SAP problems for me, just no btaudio. Did you get btaudio working
also?

You need to rmmod much more than just bttv, and then reboots shouldn't
be necessary. Loading up bttv also pulls in at least tuner, videodev,
tvaudio, i2c-algo-bit, video-buf and btcx-risc (on my system w/bttv
0.9.11). Try rmmod'ing all those too, then modprobe bttv again to get
around rebooting. Rebooting is probably easier though... :)

Same here.

I managed to fix the msp34xx problem with mine some time ago. I think
bttv was selecting the wrong card. I managed to find the right one and
dmesg would give me info about the "msp34xx found at alternate location
0x84" or some message to that effect, my memory is a little hazy. When I
did that though lirc stopped working and I had to manually configure the
driver when modprob'ing it. If I can find the settings I used again
(there around here somewhere) I'll post them to the list, someone might
find them useful. But as I said I never actually tried btaudio, so even
though I apparently had msp34xx working I never tested it.

Well, you got further than I did! If you do find those settings, I'm
definitely interested. Though that card is going to be replaced shortly
anyhow...
