Hi- I started this as a mythtv thread, trying to figure out why some recordings with my new DViCO FusionHDTV 5 lite are corrupt. My mythtv system has 1xHauppauge PVR-350, 1xHauppauge PVR-500 using ivtv 0.4, and a newly added DViCO FusionHDTV 5 Lite using DVB drivers from CVS of about a week and a half ago with kernel 2.6.14. 1x200GB seagate+1x300GB seagate HD LVM with XFS for /video and 1x40GB seagate for FC4 OS. I have DMA enabled. DVI out via fx5200 at 1280x768. Chaintech nforce2 mobo, AMD2900 with 1gb ram. All 4 tuners can capture on their own with no problems. I can capture with all 3 Hauppauge tuners at the same time no problems. Trying to capture with the FusionHDTV 5 lite while concurrently capturing with the PVR-500 tuners (either one or both) results in normal recordings. The only time I get corrupt recordings with the FusionHDTV 5 lite, is if I am concurrently trying to record with the PVR-350. The recordings just have some random scrambled bars, squares. Audio seems unaffected. Nothing shows up in dmesg or mythtv logs. I've tried removing the PVR-500, and all kinds of combinations of slots. The FusionHDTV5 lite does not share an IRQ address with either of the PVR-xxx cards. Any ideas? Any ideas where to look? Relevant parts of dmesg from card init follows. Thanks, Mike ------------------------------------------------- Linux video capture interface: v1.00 ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.4.0 (tagged release) loading ivtv: Linux version: 2.6.14-1.1637_FC4 686 REGPARM 4KSTACKS gcc-4.0 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. ivtv0: Autodetected WinTV PVR 350 card (iTVC15 based) ACPI: PCI Interrupt Link [LNK1] enabled at IRQ 11 ACPI: PCI Interrupt 0000:01:0a.0[A] -> Link [LNK1] -> GSI 11 (level, low) -> IRQ 11 ivtv0: Unreasonably low latency timer, setting to 64 (was 32) ivtv0: i2c attach to card #0 ok [client=tveeprom, addr=50] tveeprom 2-0050: Hauppauge model 48132, rev K168, serial# 7520207 tveeprom 2-0050: tuner model is LG TAPE H001F MK3 (idx 68, type 47) tveeprom 2-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 2-0050: audio processor is MSP4448 (idx 27) tveeprom 2-0050: decoder processor is SAA7115 (idx 19) tveeprom 2-0050: has radio, has IR remote tuner 2-0061: chip found @ 0xc2 (ivtv i2c driver #0) ivtv0: i2c attach to card #0 ok [client=(tuner unset), addr=61] saa7115 2-0021: saa7115 found @ 0x42 (ivtv i2c driver #0) ivtv0: i2c attach to card #0 ok [client=saa7115, addr=21] saa7127 2-0044: saa7127 found @ 0x88 (ivtv i2c driver #0) ivtv0: i2c attach to card #0 ok [client=saa7127, addr=44] msp3400 2-0040: chip=MSP4448G-A2 +nicam +simple +simpler +radio mode=simpler msp3400 2-0040: msp34xxg daemon started ivtv0: i2c attach to card #0 ok [client=MSP4448G-A2, addr=40] tda9887 2-0043: chip found @ 0x86 (ivtv i2c driver #0) ivtv0: i2c attach to card #0 ok [client=tda9887, addr=43] ivtv0: loading /lib/modules/ivtv-fw-enc.bin ivtv0: loading /lib/modules/ivtv-fw-dec.bin ivtv0: Encoder revision: 0x02050032 ivtv0: Decoder revision: 0x02020023 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 ivtv0: Allocate DMA decoder MPEG stream: 16 x 65536 buffers (1024KB total) ivtv0: Allocate DMA decoder VBI stream: 512 x 2048 buffers (1024KB total) ivtv0: Create decoder VOUT stream ivtv0: Allocate DMA decoder YUV stream: 24 x 43200 buffers (1024KB total) ivtv0: loading /lib/modules/ivtv_init_mpeg.bin tuner 2-0061: type set to 47 (LG NTSC (TAPE series)) ivtv0: Initialized WinTV PVR 350, card #0 ivtv: ====================== NEXT CARD ====================== ivtv1: Autodetected WinTV PVR 150 card (iTVC16 based) ACPI: PCI Interrupt Link [LNK4] enabled at IRQ 9 PCI: setting IRQ 9 as level-triggered ACPI: PCI Interrupt 0000:02:08.0[A] -> Link [LNK4] -> GSI 9 (level, low) -> IRQ 9 ivtv1: Unreasonably low latency timer, setting to 64 (was 32) ivtv1: i2c attach to card #1 ok [client=tveeprom, addr=50] tuner 3-0060: TEA5767 detected. tuner 3-0060: chip found @ 0xc0 (ivtv i2c driver #1) ivtv1: i2c attach to card #1 ok [client=(tuner unset), addr=60] tuner 3-0060: type set to 62 (Philips TEA5767HN FM Radio) tuner 3-0061: chip found @ 0xc2 (ivtv i2c driver #1) ivtv1: i2c attach to card #1 ok [client=(tuner unset), addr=61] tda9887 3-0043: chip found @ 0x86 (ivtv i2c driver #1) ivtv1: i2c attach to card #1 ok [client=tda9887, addr=43] tveeprom 3-0050: Hauppauge model 23552, rev D492, serial# 7855692 tveeprom 3-0050: tuner model is Philips FQ1236A MK4 (idx 92, type 57) tveeprom 3-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 3-0050: second tuner model is Philips TEA5768HL FM Radio (idx 101, type 62) tveeprom 3-0050: audio processor is CX25843 (idx 37) tveeprom 3-0050: decoder processor is CX25843 (idx 30) tveeprom 3-0050: has radio, has no IR remote ivtv1: This is the first unit of a PVR500 cx25840 3-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #1) spurious 8259A interrupt: IRQ7. cx25840 3-0044: loaded /lib/modules/HcwMakoA.ROM firmware (14264 bytes) ivtv1: i2c attach to card #1 ok [client=cx25840, addr=44] wm8775 3-001b: chip found @ 0x36 (ivtv i2c driver #1) ivtv1: i2c attach to card #1 ok [client=wm8775, addr=1b] ivtv1: Detected a TEA5767 radio tuner.
