Post subject:  R5A10 setup tuner number
well, after messing with R5A10 I've learned a few things that some other people might need to know

I have two tuners, a pvr-350 and an ATI TV Wonder VE... ivtv and bttv respectively

    1. tveeprom did not detect the correct tuner number for my pvr-350 (I always used to use options ivtv tuner=44, or in other words 44 for the tuner number) but it detected it as 47... not a big deal, but I did fix it. I'll explain a little later in the post...

    2. My ATI TV Wonder VE also did not have the correct tuner type number. I did a dmesg | grep bttv and this is what it said:
    Code:
    bttv: driver version 0.9.15 loaded
    bttv: using 8 buffers with 2080k (520 pages) each for capture
    bttv: Bt8xx card found (0).
    bttv0: Bt878 (rev 17) at 0000:00:0e.0, irq: 17, latency: 32, mmio: 0xf2800000
    bttv0: detected: ATI TV Wonder/VE [card=64], PCI subsystem ID is 1002:0003
    bttv0: using: ATI TV-Wonder VE [card=64,autodetected]
    bttv0: gpio: en=00000000, out=00000000 in=00ffffff [init]
    bttv0: using tuner=19
    bttv0: i2c: checking for TDA9875 @ 0xb0... not found
    bttv0: i2c: checking for TDA7432 @ 0x8a... not found
    bttv0: registered device video0
    bttv0: registered device vbi0
    bttv0: PLL: 28636363 => 35468950 .. ok
    bttv0: PLL can sleep, using XTAL (28636363).

    this was bad because it should say bttv0: using tuner=2.

sooo... to fix both of these issues I just edited /etc/modprobe.conf so it looks like this:



Code:
mythtv@mythtv:~ $ more /etc/modprobe.conf
options bttv tuner=2
options ivtv tuner=44


but I will say that I can NOT record from both cards at the same time... the pvr-350 stops recording, but if I'm only watching tv or ONLY recording with the pvr-350 or only with the tv wonder ve then it works fine... I'm still working on this.

What issues were you experiencing with the 350 that made you want to change the tuner type number?

I have a 350 and am wondering if I should be looking into doing this.

Thanks

well actually... I changed it to 44, then I recently changed it back to 47 because I believe that's what it should be... I do get shadowy lines on channels like 63... but I don't think it's a big deal... if anyone has any insight on if using the wrong tuner affects things other then what you see... as in if you have a different tuner type then what it should be could make your system unstable.... then any insight would be helpful

Thanks for your quick response, I guess I will just stay put with this since I have bigger isues (TV-OUT) to be fine tuning yet :-)

this is close to what I am looking for
I have my system up and running thanks to the forums

Chaintech nif2 board
pvr250
sempron 2300
512 ram
samsung dvd
160 gb h drive

r5A15

Initial install I also had a bt878 tuner in I got no TV at all
I reinstalled with just the pvr250......Success

---side note Following the readme file to install the Nvidia drivers did not work for me IE untared source no problem but when I ran install-nv {tab} nothing happened. Anyway searched the mforums and installed them following a couple of posts.

On to my question (I have searched that is how I found this post :) )
When I put back in my bt878 card how can I tell the correct tuner type?

When it was in before I ran grep tuner and it seemed to say 21 if I was reading the output correctly. Is that what it is trying to use or is that the correct # and what I should add to the modprobe.conf file?

Thanks

Ps followed the directions and the grey remote worked like a charm.
