Hi, I have posted this on the users mail list, but have had no help. I hope maybe if any of the Developer team can please help me out?
I am using IVTV drivers, primarily with MythTV, which up until recently worked perfectly. I did a re-install a couple of weeks ago, FC6 (kernel 2.6.20-1.2948.fc6 #1 SMP) and since then I have had a really weird problem. Most of the time the video is fine, but if text comes up on the screen such as a screen bug, ident or test in an advert, the picture starts to flicker and scramble and the sound gets really choppy. This is really confusing me, because it is not text overlaid by the PC, but text in the channel I am watching. I am using the SVHS input on the card, a Hauppauge PVR-150MCE, which is being fed by a UK Sky Digital Decoder/set top box. I have checked the video signal coming from Sky and that is clean. The same problem occurs if I use a terrestrial antenna and watch analouge free-to-air channels. It is not Myth as far as I can tell as I have tried Mplayer to play video directly from /dev/video0. Also I can used Cat to grab some video and the same thing happens. This is not something I have seen happen before, and I have tried 2 re-installs since to see if that helps, but it is always the same. Can anyone make any suggestion as to what might be going on. I have tried disabling Hyper-Threading which I saw was mentioned in one post, but that has had no effect. There is nothing in any of the logs to indicate a problem. As I mentioned, I'm running Core 6 on a P4 3ghz with Hyperthreading. I've got 512mb of Ram, and 200gb of hard disk. ATI Radeon X300 lo-profile video card using the ATI official drivers (also tried FC's drivers with the same result). The effect is the same if I am using DVI, VGA or S-VHS output on the video card. I installed IVTV using yum and the ATRpm's repository as recommended on Jerod Wilson's Fedora-Mythology guide. This is always what I've done before with out this occuring. Everything seems to get loaded alright, here is the log regarding that : ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.10.1 (tagged release) loading ivtv: Linux version: 2.6.20-1.2948.fc6 SMP mod_unload 686 4KSTACKS 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 card (cx23416 based) ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16 lirc_mceusb2[2]: Philips eHome Infrared Transceiver on usb3:2 usbcore: registered new interface driver lirc_mceusb2 ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 16 (level, low) -> IRQ 16 PCI: Setting latency timer of device 0000:00:1b.0 to 64 hda_codec: Unknown model for ALC880, trying auto-probe from BIOS... sd 1:0:0:0: Attached scsi generic sg0 type 0 ieee1394: Host added: ID:BUS[0-00:1023] GUID[0010dc00009787e3] ivtv0: loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv0: Encoder revision: 0x02060039 tveeprom 1-0050: Hauppauge model 25019, rev B157, serial# 7750383 tveeprom 1-0050: tuner model is Philips FM1216 ME MK3 (idx 57, type 38) tveeprom 1-0050: TV standards PAL(B/G) PAL(I) SECAM(L/L') PAL(D/D1/K) (eeprom 0x74) 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 receiver, has no IR transmitter ivtv0: Autodetected Hauppauge WinTV PVR-150 tuner 1-0043: chip found @ 0x86 (ivtv i2c driver #0) tda9887 1-0043: tda988[5/6/7] found @ 0x43 (tuner) tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #0) cx25840 1-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #0) cx25840 1-0044: loaded v4l-cx25840.fw firmware (16382 bytes) wm8775 1-001b: chip found @ 0x36 (ivtv i2c driver #0) ivtv0: Registered device video0 for encoder MPEG (4 MB) ivtv0: Registered device video32 for encoder YUV (2 MB) ivtv0: Registered device vbi0 for encoder VBI (1 MB) ivtv0: Registered device video24 for encoder PCM audio (1 MB) ivtv0: Registered device radio0 for encoder radio tuner 1-0061: type set to 38 (Philips PAL/SECAM multi (FM1216ME MK3)) ivtv0: Initialized Hauppauge WinTV PVR-150, card #0 ivtv: ==================== END INIT IVTV ==================== Any ideas anyone?
