At first glance, the card appears to be working perfectly under Suse 11.1, Ubuntu 8.10 and Windows XP. However, when recording videos under Suse 11.1 or Ubuntu 8.10 (mencoder or ffmpeg),there are statistical "jerks" in the pictures, about once every few minutes. These are best detected during slow panning of the camera. Closer inspection shows that one field of an earlier frame, e.g. 4 frames back, is interlaced with the present frame, causing a short jump up/down or sideways in this picture. I have good screen copies, if someone is interested. When de-interlacing, one just gets the average of the two fields not belonging together. This does not happen at all under Windows, just the Linux systems. 100 different recording options (even rawvideo), formats etc. did not change anything. The problem is not related to cpu load. Meanwhile I am sure that tv play-back with vlc or mplayer also has these jerks (difficult to prove without replay). Changing more or less all relevant driver options - buffers, latency, overlay - made no difference. I would be most grateful, if anyone could help. Thank you and best regards Kurt System: openSUSE 11.1 (x86_64) Kernel 2.6.27.7-9-default or Ubuntu 8.10 (i386 or amd64, 2.6.27-11) CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ (Family: 15, Model: 75, Stepping: 2) CPUflags: Type: 15 MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 1 Driver: version of the Kernels saa7130/34: v4l2 driver version 0.2.14 loaded saa7134 0000:04:08.0: PCI INT A -> Link[APC1] -> GSI 16 (level, low) -> IRQ 16 saa7134[0]: setting pci latency timer to 64 saa7134[0]: found at 0000:04:08.0, rev: 1, irq: 16, latency: 64, mmio: 0xfdbff000 saa7134[0]: subsystem: 1131:0000, board: Tevion MD 9717 [card=6,insmod option] Modules linked in: saa7134(+) snd_emu10k1(+) ir_common snd_rawmidi snd_ac97_codec compat_ioctl32 ac97_bus snd_hda_intel snd_seq_device videodev v4l1_compat snd_pcm snd_util_mem v4l2_common ppdev snd_timer videobuf_dma_sg videobuf_core snd_page_alloc snd_hwdep emu10k1_gp snd parport_pc rtc_cmos dcdbas(X) tveeprom i2c_nforce2 rtc_core button gameport parport rtc_lib tg3 i2c_core soundcore k8temp(N) floppy pcspkr libphy sr_mod cdrom sg sd_mod crc_t10dif ehci_hcd ohci_hcd usbcore edd ext3 mbcache jbd fan ide_pci_generic ide_core ata_generic sata_nv libata scsi_mod dock thermal processor thermal_sys hwmon [] saa7134_initdev+0x429/0x874 [saa7134] saa7134[0]: board init: gpio is 100a0 saa7134[0]: Huh, no eeprom present (err=-5)? saa7134[0]: i2c scan: found device @ 0xc0 [tuner (analog)] tuner' 2-0060: chip found @ 0xc0 (saa7134[0]) saa7134[0]: registered device video0 [v4l2] saa7134[0]: registered device vbi0 saa7134[0]: registered device radio0 04:08.0 Multimedia controller: Philips Semiconductors SAA7134/SAA7135HL Video Broadcast Decoder (rev 01) Subsystem: Philips Semiconductors Device 0000 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR-
