Hi folks. I am troubleshooting a noisy picture coming from the upper channels on my PVR 500. An MPEG2 file which illustrates this is available at this url: http://www.ellissoftworks.com/noisy-pvr500.mpg
This test file was captured by executing the following commands: $ ivtv-tune -c 62 /dev/video0 $ cat /dev/video0 > noisy-pvr500.mpg At first, I assumed I had a noisy cable configuration. So, I replaced the cable connecting my PVR500 to the wall, and the problem persisted. Following that, I connected the cable directly to the TV's built-in tuner, and I found that the image was fine when acquiring it via the TV's tuner, but using the same cabling, the PVR500 delivered the noisy image. The first few channels (2-13 or so) are perfect, and channels from 13-40 or a little noisy. Above that, you get results such as the example I provided above (that one's channel 62). It's worth mentioning that this has not been a problem in the past (prior to last month, I was using IVTV 0.6.4). So, I reverted to 0.6.4, but that did not correct the issue either. My configuration information appears below. Any suggestions as to what I might try? Could this be a hardware problem? Thanks for your thoughts. -Mike Ellis Linux video capture interface: v1.00 ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.6.7 (tagged release) loading ivtv: Linux version: 2.6.16-gentoo-r13 SMP gcc-3.4 ivtv: In case of problems please include the debug info between ivtv: the START INIT IVTV and END INIT IVTV lines, along with ivtv: any module options, when mailing the ivtv-users mailinglist. ivtv0: Autodetected Hauppauge WinTV PVR-150 card (cx23416 based) ACPI: PCI Interrupt Link [APC1] enabled at IRQ 16 GSI 20 sharing vector 0x32 and IRQ 20 ACPI: PCI Interrupt 0000:05:08.0[A] -> Link [APC1] -> GSI 16 (level, low) -> IRQ 50 ivtv0: Unreasonably low latency timer, setting to 64 (was 32) tveeprom 0-0050: Hauppauge model 23552, rev E587, serial# 8382698 tveeprom 0-0050: tuner model is Samsung TCPN 2121P30A (idx 87, type 70) tveeprom 0-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 0-0050: second tuner model is Philips TEA5768HL FM Radio (idx 101, type 62) tveeprom 0-0050: audio processor is CX25843 (idx 37) tveeprom 0-0050: decoder processor is CX25843 (idx 30) tveeprom 0-0050: has radio, has no IR remote ivtv0: This is the first unit of a PVR500 tuner 0-0060: TEA5767 detected. tuner 0-0060: chip found @ 0xc0 (ivtv i2c driver #0) tuner 0-0060: type set to 62 (Philips TEA5767HN FM Radio) tuner 0-0061: chip found @ 0xc2 (ivtv i2c driver #0) cx25840 0-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #0) cx25840 0-0044: loaded v4l-cx25840.fw firmware (16382 bytes) wm8775 0-001b: chip found @ 0x36 (ivtv i2c driver #0) ivtv0: loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv0: Encoder revision: 0x02060039 ivtv0: Allocate DMA encoder MPEG stream: 128 x 32768 buffers (4096KB total) ivtv0: Allocate DMA encoder YUV stream: 194 x 10800 buffers (2048KB total) ivtv0: Allocate DMA encoder VBI stream: 120 x 17472 buffers (2048KB total) ivtv0: Allocate DMA encoder PCM audio stream: 455 x 4608 buffers (2048KB total) ivtv0: Create encoder radio stream tuner 0-0061: type set to 70 (Samsung TCPN 2121P30A) ivtv0: Initialized WinTV PVR 500 (unit #1), card #0 ivtv: ====================== NEXT CARD ====================== ivtv1: Autodetected Hauppauge WinTV PVR-150 card (cx23416 based) ACPI: PCI Interrupt Link [APC2] enabled at IRQ 17 GSI 21 sharing vector 0x3A and IRQ 21 ACPI: PCI Interrupt 0000:05:09.0[A] -> Link [APC2] -> GSI 17 (level, low) -> IRQ 58 ivtv1: Unreasonably low latency timer, setting to 64 (was 32) tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #1) cx25840 1-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #1) cx25840 1-0044: loaded v4l-cx25840.fw firmware (16382 bytes) wm8775 1-001b: chip found @ 0x36 (ivtv i2c driver #1) tveeprom 1-0050: Hauppauge model 23552, rev E587, serial# 8382698 tveeprom 1-0050: tuner model is Samsung TCPN 2121P30A (idx 87, type 70) tveeprom 1-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 1-0050: second tuner model is Philips TEA5768HL FM Radio (idx 101, type 62) tveeprom 1-0050: audio processor is CX25843 (idx 37) tveeprom 1-0050: decoder processor is CX25843 (idx 30) tveeprom 1-0050: has radio, has no IR remote ivtv1: This is the second unit of a PVR500 ivtv1: Correcting tveeprom data: no radio present on second unit ivtv1: loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv1: Encoder revision: 0x02060039 ivtv1: Allocate DMA encoder MPEG stream: 128 x 32768 buffers (4096KB total) ivtv1: Allocate DMA encoder YUV stream: 194 x 10800 buffers (2048KB total) ivtv1: Allocate DMA encoder VBI stream: 120 x 17472 buffers (2048KB total) ivtv1: Allocate DMA encoder PCM audio stream: 455 x 4608 buffers (2048KB total) tuner 1-0061: type set to 70 (Samsung TCPN 2121P30A) eth0: no IPv6 routers present ivtv1: Initialized WinTV PVR 500 (unit #2), card #1 ivtv: ==================== END INIT IVTV ==================== ========================= Michael F.
