| Post subject: | Pvr-250 and Winfast200 installation |
I have successfully installed a pvr-250 and winfast 2000 tuner card in the same box. The pvr-250 is my primary card and the Winfast is my secondary. When I use PIP the Winfast 2000 display in the upper left hand corner of the screen. When I toggle out of PIP live TV freezes, and a dialog is presented stating that I have lost connection to the backend. The following is in the mythtvbackend.log. Any suggestions? Thanks, MIke G. open: Device or resource busy 2004-05-18 21:52:50 Could not open audio device: /dev/dsp 2004-05-18 21:52:50 Changing from None to WatchingLiveTV Unknown video codec Please go into the TV Settings, Recording Profiles and setup the four 'Software Encoders' profiles.

I setup the 'Software Encoders' profile and the problem still persists. The following is from the backend log. It is slightly different from the original log message that I posted. I believe that the error has something to do with the sound capture of my sound card. The Winfast 2000 sound gets captured from the line in. Any suggestions?

Ok I think I know why I am having this problem I just don't know how to solve it. I can view TV/audio with my pvr-250 fine. I switch to the WinFast capture card <Y> I can view TV/audio with the Winfast2000 fine. When I switch back to the pvr-250 the TV.audio for the pvr-250 is fine but I also hear the audio from the Winfast2000 which I have just switched from. When I use PiP the Winfast is not giving up the audio therefore the pvr-250 hangs. This must be a configuration error either in mythtv-setup or modules.config. Both cards are setup for /dev/dsp. I also tried the Winfast with /dev/dsp1 and still had the same results. I have also upgraded the bttv driver. Any suggestions? Thanks, Mike G. |

Have you searched or posted to the MythTV mailing list? |

well I don't think the /dev/dsp is the problem, because even though the pvr250 is setup for /dev/dsp it never really uses the device. It muxes the audio in with the video stream in hardware. and I'm not really sure why you are having the problem. I have a leadtek and pvr250, and pip works just fine for me. I've never tried the Y to switch cards though. |

Xsecrets, Which tuner is your primary tuner? Thanks, Mike G. |

The pvr250 of course. it is not /dev/video0. for some reason I could not get it to detect the pvr first no matter what I did, but doesn't seem to bother anything. I just set it up first in the database. |

Xsecrets, So far I can't seem to detect any differences so I have a couple of more questions. 1. It sounds like you started with r4v2 have you upgraded since and how, "Auto Upgrade" or apt-get 2. what are you running for v4l? I am running v4l2. 3. what are you running for bttv? I am running 9.15. Thanks, Mike G. mythtv@mythtv:~ $ dmesg | grep v4l ivtv: Registered v4l2 device, minor 0 ivtv: Registered v4l2 device, minor 32 ivtv: Registered v4l2 device, minor 224 mythtv@mythtv:~ $ dmesg | grep bttv tuner: tv aard core driver (bttv, saa7134, ...) instead. 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 01:08.0, irq: 5, latency: 32, mmio: 0xdc000000 bttv0: detected: Leadtek WinFast TV 2000 [card=34], PCI subsystem ID is 107d:6606 bttv0: using: Leadtek WinFast 2000/ WinFast 2000 XP [card=34,autodetected] bttv0: gpio: en=00000000, out=00000000 in=00bf7707 [init] tuner: tv aard core driver (bttv, saa7134, ...) instead. bttv0: using tuner=5 bttv0: i2c: checking for MSP34xx @ 0x80... not found bttv0: i2c: checking for TDA9875 @ 0xb0... not found bttv0: i2c: checking for TDA7432 @ 0x8a... not found bttv0: registered device video1 bttv0: registered device vbi1 bttv0: registered device radio0 bttv0: PLL: 28636363 => 35468950 .. ok bttv0: PLL can sleep, using XTAL (28636363). |

well I started on R4 then reinstalled with R4V2 then I reinstalled again with R4V3, but the wireless drivers suck in the new kernel, and I was getting hit with the red bug from the new bttv v4l2 so I did an autoupgrade to downgrade back to R4V2 and that's what I'm running now. R4V2 with the tv_grab_na_dd fix. so I am using v4l not sure what the version of bttv is, but certainly not the newest. |

Ok, all I can think of doing now is to downgrade from v4l2 to v4l. I was going to do this by updating the kernel to pchdtv. Will I have problems with a pvr-250 and winfast 2000 if I upgrade the kernel to pchdtv? There is a statement in the README thas says that ivtv and pcHDTV current don't work together. Please advise. Thanks, Mike G. |

You shouldn't have any issue as you aren't using the two cards together(ivtv and pcHDTV). |

one other thing to make sure you are not using xvmc. pip does not ever work with xvmc. |
