Is it tuned to the right channel/frequency/source input? "cat /dev/video1" itself lacks the ability to control the device and therefore you won't be able to test the driver's ability to change channels, for example, without relying on another application. -- Chaogui Zhang ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

In my experience, it is generally easier to test a new driver if you use simpler applications such as tvtime, azap/dvbscan. These programs will tell you pretty quickly whether the device and its driver are working properly or not. Once you are sure the drivers are working properly, then move on to your favorite media center or any other program. Trying to test device driver with MythTV sometimes muddles the water too much and you won't know whether it is a problem with the driver or the application. -- Chaogui Zhang ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

That's not to say that the driver doesn't work, I'm sure its something I trying to do. The DVB portion is working fine. I'm trying to test using MythTV. First off the driver is creating 2 video devices in /dev. I'm guessing that one of them is the analog card with MPEG2 encoder support and the other is just a the frame grabber. When I select /dev/video1 ( I used ivtv_first_minor to move off the PVR500 /dev links ) in the MythTV setup it recognizes the card ( probes correctly ) and shows me what my inputs are to select from. I chose Television ( vs s-video etc ). When I attempt to watch LiveTV it just never starts. Actually it does start, and then exits back to the menu. The frontend doesn't see a recording file being generated. I can cat /dev/video1 to a file and get audio and video. But the video is super dark. I can barely make out any shapes. But the audio is fine. -- No virus found in this outgoing message. Checked by AVG Free Edition.
