I'm having a bit of trouble getting my PVR-250 card to work, or more precisely tune correctly. The symptoms are that I can insert all the drivers (ivtv, tuner, without any errors, however when I use mplayer to view /dev/video0 I get what looks like a scrambled TV station (i.e. not quite B&W static, but a really fuzzy image with bars that jumps all over the place, and looks like a really badly tuned TV station). This is a card from almost 2 years ago, so I'm pretty sure it's not that I have a new tuner that isn't supported (that and it worked a while ago).
I'm running gentoo (2004.3), using kernel 2.6.9-gentoo-r6 (preempt), with an older PVR-250 card (Tuner type=2 according to the ivtv module's detection. I've also tried setting the tuner type manually to 39 in case I had the newer LG tuner with no luck) on an Athlon 2600+, using an nForce2 chipset. Here's what I've tried to no success already: 1. I figured I was using the wrong frequency tables and switched between us-cable, us-cable-hrc, and even tried us-bcast just to make sure (BTW I'm in Baltimore Maryland using Comcast standard cable as my source) with no success. I was using the ptune-ui.pl script to do this while watching video in mplayer. 2. I tried using different versions of the driver. I started out with 0.2.0_rc3 from the gentoo portage tree, then switched back to 0.1.10-pre2-ck71d, and am now running 0.3.1z (although the ivtv kernel log says it's 0.3.1y). All load correctly and have no errors as far as I can see (well other than not working :). 3. I've checked that the video source is good by doing the testing with a TV plugged into the same source as the PVR-250 card is, and the TV is able to tune properly. 4. I've tried various versions of the firmware all to no avail. Next in the list to try is switching back to a 2.4.x kernel, but before I do that I figured I'd post here and see if anyone could quickly point out something I'm doing wrong. I've had this card working about a year and a half ago in an older PII running slackware and a 2.4.x kernel, so I'm pretty sure the hardware is good. I've included the kernel log messages below, as well as an lsmod, and the firmware versions I'm using. Any help would be appreciated :) -Kevin Ulmes MD5 hashes of the firmware I'm using: 305dba74bbe5905447add8883f3ecb68 ivtv-fw-dec.bin ab75947ef1b086e26f9b08e628baa02e ivtv-fw-enc.bin Kernel Log: Linux video capture interface: v1.00 tuner: Ignoring new-style parameters in presence of obsolete ones ivtv: Unknown parameter `mpg_buffers' ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.3.1 (y) loading ivtv: Linux version: 2.6.9-gentoo-r6 preempt K7 gcc-3.3 ivtv: In case of problems please include the debug info ivtv: between the START INIT IVTV and END INIT IVTV lines when ivtv: mailing the ivtv-devel mailinglist. ivtv: Autodetected WinTV PVR 250 card ivtv: Found an iTVC16 based chip ACPI: PCI interrupt 0000:01:07.0[A] -> GSI 5 (level, low) -> IRQ 5 ivtv: Unreasonably low latency timer, setting to 64 (was 32) ivtv: XXX PCI device: 0x01e0 vendor: 0x10de msp34xx: ivtv version msp34xx: init: chip=MSP3435G-B6, has NICAM support, simple (D) mode, simpler (G) no-thread mode msp34xx: $Id$ compiled on: Dec 11 2004 23:34:39 ivtv: i2c attach [client=MSP3435G-B6,ok] saa7115: starting probe for adapter ivtv i2c driver #0 (0x10005) saa7115: detecting saa7115 client on address 0x42 saa7115: writing init values ivtv: i2c attach [client=saa7115[0],ok] saa7115: status: (1E) 0x48, (1F) 0xc0 tuner: chip found at addr 0xc2 i2c-bus ivtv i2c driver #0 ivtv: i2c attach [client=(tuner unset),ok] tveeprom: Hauppauge: model = 32031, rev = B210, serial# = 6196441 tveeprom: tuner = Philips FI1236 MK2 (idx = 10, type = 2) tveeprom: tuner fmt = NTSC(M) (eeprom = 0x08, v4l2 = 0x00001000) tveeprom: audio_processor = MSP3435 (type = 10) ivtv: i2c attach [client=tveeprom[0],ok] ivtv: Tuner Type 2, Tuner formats 0x00001000, Radio: yes, Model 0x00892450, Revision 0x00000000 ivtv: NTSC tuner detected ivtv: Radio detected ivtv: Encoder revision: 0x02040011 ivtv: Configuring WinTV PVR 250 card with 5 streams ivtv: Create DMA stream 0 using 256 16384 byte buffers 4194304 kbytes total ivtv: Registered v4l2 device, streamtype 0 minor 0 ivtv: Create DMA stream 1 ivtv: Registered v4l2 device, streamtype 1 minor 32 ivtv: Create stream 2 using 40 52224 byte buffers 2097152 kbytes total ivtv: Registered v4l2 device, streamtype 2 minor 224 ivtv: Create DMA stream 3 using 455 4608 byte buffers 2097152 kbytes total ivtv: Registered v4l2 device, streamtype 3 minor 24 ivtv: Create stream 4 ivtv: Registered v4l2 device, streamtype 4 minor 64 ivtv: Setting Tuner 2 tuner: type set to 2 (Philips NTSC (FI1236,FM1236 and compatibles)) by ivtv i2c driver #0 saa7115: decoder set input (4) saa7115: now setting Composite input ivtv: Setting audio matrix to input 3, output 1 ivtv: Switching standard to NTSC. ivtv: ivtv_enc_thread: pid = 6723, itv = 0xe1991820 saa7115: decoder set norm NTSC saa7115: set audio: 0x01 ivtv: Initialized WinTV PVR 250, card #0 ivtv: ==================== END INIT IVTV ==================== Lsmod: Module Size Used by bttv 145356 0 video_buf 17156 1 bttv firmware_class 7808 1 bttv v4l2_common 5120 1 bttv btcx_risc 3976 1 bttv lirc_i2c 6916 0 lirc_dev 10892 2 lirc_i2c tveeprom 11060 0 ivtv 806660 1 tuner 18852 0 saa7115 11416 0 msp3400 26168 0 i2c_algo_bit 8584 2 bttv,ivtv i2c_core 19216 7 bttv,lirc_i2c,tveeprom,tuner,saa7115,msp3400,i2c_algo_bit videodev 7552 2 bttv,ivtv snd_pcm_oss 48552 0 snd_mixer_oss 17792 1 snd_pcm_oss snd_seq_oss 31744 0 snd_seq_midi_event 6400 1 snd_seq_oss snd_seq 49424 4 snd_seq_oss,snd_seq_midi_event usbcore 102116 1 snd_intel8x0 29900 0 snd_ac97_codec 68816 1 snd_intel8x0 snd_pcm 84872 2 snd_pcm_oss,snd_intel8x0 snd_timer 21380 2 snd_seq,snd_pcm snd_page_alloc 7688 2 snd_intel8x0,snd_pcm gameport 3712 1 snd_intel8x0 snd_mpu401_uart 6272 1 snd_intel8x0 snd_rawmidi 20260 1 snd_mpu401_uart snd_seq_device 6536 3 snd_seq_oss,snd_seq,snd_rawmidi snd 47716 11 snd_pcm_oss,snd_mixer_oss,snd_seq_oss,snd_seq,snd_intel8x0,snd_ac97_codec,sn d_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device forcedeth 14848 0 ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
