I'm trying to collect data to see if motherboards with PCI v2.2 chipsets or older have a problem with this device or not. > Another reboot for good measure and both /dev/video0 > and /dev/dvb/xxyyzz are created, no errors in dmesg.

I like and use MythTV as my PVR software. However, it's a poor tool to use for diagnosis; it introduces too many other variables and offers little insight. For testing NTSC, please use: $ cat /dev/video0 > test.mpg and any tool you want to view or inspect the test.mpg file. You can use ivtv-tune to change to a particular channel before or during capture. Or use mplayer to test, something like: $ mplayer -cache 8192 /dev/video0 Where MythTV gives you a blanks screen and (default) sparse logging, mplayer will usually output quite a few detailed error messages. Again, I find ivtv-tune convenient for changing channels, but I think v4l2-ctl will let you change frequencies as well. > I have debugging set at 3 at the moment, but no errors are generated. > Please let me know what information you need to identify the issue. For the tuner module you may want to set the debug level higher. I just tested with "modprobe tuner debug=5", not knowing what the effect would be but it seemed more verbose than using "debug=1". For the cx18 module you may also want to turn on the i2c debug flag (debug=67) and *maybe* the high volume flag (debug=323) if you still don't see anything unusual. If you use high volume, you may have to look in /var/log/messages and the dmesg ring buffer may not hold it all. But as a troubleshooting step, first let's eliminate if it's the NTSC tuner, or some other issue down the line. What is the status of the analog tuning using v4l2-ctl? Here's an example status log showing proper tuning of US broadcast channel 4: $ ./v4l2-ctl -d /dev/video0 --log-status Status Log: cx18-0: ================= START STATUS CARD #0 ================= tveeprom 1-0050: Hauppauge model 74041, rev C5B2, serial# 891351 tveeprom 1-0050: MAC address is 00-0D-FE-0D-99-D7 tveeprom 1-0050: tuner model is TCL M2523_5N_E (idx 112, type 50) tveeprom 1-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 1-0050: audio processor is CX23418 (idx 38) tveeprom 1-0050: decoder processor is CX23418 (idx 31) tveeprom 1-0050: has no radio, has IR receiver, has IR transmitter cx18-0: Video signal: present cx18-0: Detected format: NTSC-M cx18-0: Specified standard: NTSC-M cx18-0: Specified video input: Composite 7 cx18-0: Specified audioclock freq: 48000 Hz cx18-0: Detected audio mode: stereo with SAP cx18-0: Detected audio standard: BTSC cx18-0: Audio muted: no cx18-0: Audio microcontroller: running cx18-0: Configured audio standard: automatic detection cx18-0: Configured audio system: BTSC cx18-0: Specified audio input: Tuner (In8) cx18-0: Preferred audio mode: stereo cs5345 1-004c: Input: 1 cs5345 1-004c: Volume: 0 dB tuner 2-0061: Tuner mode: analog TV tuner 2-0061: Frequency: 67.25 MHz tuner 2-0061: Standard: 0x00001000 cx18-0: Video Input: Tuner 1 cx18-0: Audio Input: Tuner 1 cx18-0: GPIO: direction 0x00003001, value 0x00003001 cx18-0: Tuner: TV cx18-0: Stream: MPEG-2 Program Stream cx18-0: VBI Format: No VBI cx18-0: Video: 720x480, 30 fps cx18-0: Video: MPEG-2, 4x3, Variable Bitrate, 6000000, Peak 8000000 cx18-0: Video: GOP Size 15, 2 B-Frames, GOP Closure cx18-0: Audio: 48 kHz, Layer II, 224 kbps, Stereo, No Emphasis, No CRC cx18-0: Spatial Filter: Manual, Luma 1D Horizontal, Chroma 1D Horizontal, 0 cx18-0: Temporal Filter: Manual, 8 cx18-0: Median Filter: Off, Luma [0, 255], Chroma [0, 255] cx18-0: Status flags: 0x00200001 cx18-0: Stream encoder MPEG: status 0x0118, 1% of 2016 KiB (63 buffers) in use cx18-0: Stream encoder YUV: status 0x0000, 0% of 2048 KiB (16 buffers) in use cx18-0: Stream encoder PCM audio: status 0x0000, 0% of 1008 KiB (63 buffers) in use cx18-0: Read MPEG/VBI: 148908032/0 bytes cx18-0: ================== END STATUS CARD #0 ================== > Michael > > ##### dmesg ########## > 120.016694] Linux video capture interface: v2.00 > [ 120.055132] cx18: Start initialization, version 1.0.0 > [ 120.055203] cx18-0: Initializing card #0 > [ 120.055207] cx18-0: Autodetected Hauppauge card > [ 120.055212] cx18-0 info: base addr: 0xe4000000 > [ 120.055214] cx18-0 info: Enabling pci device > [ 120.055236] ACPI: PCI Interrupt 0000:05:09.0[A] -> GSI 18 (level, low) -> IRQ 18 > [ 120.055252] cx18-0 info: cx23418 (rev 0) at 05:09.0, irq: 18, latency: 66, memory: 0xe4000000 A latency timer of 66 is a little odd, not being a multiple of 8 PCI clocks.

I assume you switch from 400 MHz to a real TV station before testing. When my driver loads (I haven't updated in a few days), it automatically changes over to US broadcast channel 4 at 67.25 MHz.
