For the longest time, the "default" was the television input, US Broadcast channel 7. However a while back (after NTSC OTA went dark in the USA) I changed the default to US Broadcast channel 3 - to match the RF modulator I had laying around so as to make it easy to continue testing. It's possible that you just now switched to a kernel with a driver that is defaulting to channel 3 instead of 7.... You can use the driver's sysfs interface to control all of this right from the shell command line. Failing that you will need to run a V4L app in order to set the input (e.g. "television" vs "s-video" vs "composite" vs "radio" in your case) and in the case of "television" or "radio" also set the tuned frequency. Otherwise you're probably not getting a valid signal which would explain the results you're seeing. > 5.

Those missing headers are for support of specific v4l-dvb tuners having to do with later model devices (like the HVR-1950). The standalone driver supports all that, and the kernel version you're compiling against (2.6.32) should also support that. However I've seen cases where a distro vendor's kernel source package fails to include *all* of the headers for that kernel. Sometimes the distro might split the headers into multiple packages, in which case you would need to identify and install those other packages. > > Anyone else experience the "green screen" and digital noise in the mpeg > stream?
