It's default resolution for the bttv card is 480x480, so I'm not sure what's happening here. On other attempts I've seen it start up at 720x480. > > OK. Some questions and things to try: > > 1.

This is an nForce4 board, with PCIe, so I believe that pretty much guarantees that it's PCI 2.3. In addition I verified that I have a subtractive pci bridge, if I remember your earlier posts. I did as you suggested there, and read the whole i2c/pci thread, and I think I'm good. > 2.

I just reconnected the coax to the output of the splitter, and that feeds the bttv card just fine. Then the "cx18-0: Specified video input: Composite 7" would make me think that I'm not looking at the tuner input, but "v4l2-ctl -d /dev/video1 --show" gives: Driver Info: Driver name : cx18 Card type : Hauppauge HVR-1600 Bus info : 0000:05:08.0 Driver version: 65536 Capabilities : 0x01030001 Video Capture Tuner Audio Read/Write Format Video Capture: Width/Height : 720/480 Pixel Format : MPEG Field : Interlaced Bytes per Line: 0 Size Image : 131072 Colorspace : Broadcast NTSC/PAL (SMPTE170M/ITU601) Format VBI Capture: Sampling Rate : 27000000 Hz Offset : 248 samples (9.18519e-06 secs after leading edge) Samples per Line: 1452 Sample Format : GREY Start 1st Field : 10 Count 1st Field : 12 Start 2nd Field : 273 Count 2nd Field : 12 Crop Capability Video Capture: Bounds : Left 0, Top 0, Width 720, Height 480 Default : Left 0, Top 0, Width 720, Height 480 Pixel Aspect: 10/11 Video input : 0 (Tuner 1) Audio input : 0 (Tuner 1) Frequency: 0 (0.000000 MHz) Video Standard = 0x00001000 NTSC-M Tuner: Capabilities : 62.5 kHz stereo lang1 lang2 Frequency range : 0.0 MHz - 0.0 MHz Signal strength : 0% Current audio mode : lang1 Available subchannels: mono Which would indicate that the tuner is the live input. > 4.

VDec: vo config request - 720 x 480 (preferred colorspace: Planar YV12) VDec: using Planar YV12 as output csp (no 0) Movie-Aspect is 1.33:1 - prescaling to correct movie aspect. VO: [x11] 720x480 => 720x540 Planar YV12 By the way, should I be doing a "modprobe ivtv" prior to "modprobe cx18"? When I was fooling around with it the other night, I noticed that loading ivtv first did change the symptoms, and may have increased the apparent functionality, though I may also be interpreting that wrong. I notice that there doesn't appear to be any direct dependence between ivtv and cx18, though both do use several other modules. I also thought I saw that cx18 used pieces (as in source code) of ivtv, but didn't depend directly on it. Is it also possible that ivtv is hurting? A quick "rmmod ivtv cx18 && modprobe cx18", and the v4l2-ctl command above gives the same results. I think the crux of my problem is the lack of video signal, but don't understand it.
