I plan on heading into tonn tomorrow to get an s-video cable nonetheless, but any idea as to what is happening?
If you are using an external device with it's own tuner and connecting it by coax to the tuner of the capture card, the capture card tuner needs to remain on channel 3 (or 4 is the other common channel) no matter which channel the external device is tuned to. Myth has an option for this situation. First, establish if there is an over the air channel in your area for three or four. Unless you are midway between metropolitan areas, there will normally be one or the other and not both. Set the output of the external box to the unused channel. I'll assume you've gotten this right but if there is a local channel 3, switch the box to 4. Run mythtv-setup. Go to Input connections and choose the tuner input. Select the Video source. Because you don't have an IR blaster and script yet, use "/bin/true" and the "External channel change command" If you had left this blank, that may have been the problem. If the external command is set and you are using the coax tuner input, set the "Preset tuner to channel" to match the output channel of the external box. The effect will be that when you change to channel 23, "/bin/true 23" will return success and the tuner on the card will stay on the preset channel. You will get a better picture by using s-video. The cable keeps the luma and chroma signals separate and only caries video. The external box will have red and white audio output RCA jacks. Your card most likely has a 1/8" stereo audio input jack. Therefore, you will need to get a two female RCA to 1/8" stereo jack adapter along with a stereo 2 wire RCA cable for the length you'll need if you don't have one already. NOTE: the adapter should have color coded RCA connectors (normally red and white) and 3 contacts on the 1/8" jack. There are also splitters or combiners with two unmarked RCA to a mono 1/8" jack. This is not what you want. The adapter you what should look something like one of these: http://www.lg-internet.com/catalog/images/CBL%203.5MM%202%20RCA.jpg http://www.audiogear.com/Resources/~Adpt2RcfMsm When you get the s-video wired up, run mythtv-setup again. Set the tuner input video source to "(None)" to disable it. Set the video source for the s-video, "/bin/true" for your temporary external command, and leave the preset blank. -- bjm _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
