if the cable box is on, than that's the only point. so if it's on a music station or just has a logo, then it's not a pure black image and that means the cable box is on and the channel change command will work, right? If there is something like a logo that goes around the screen and you have to hit "select" to view TV then I would think the rest of the screen is still going to be black and that just means you would change the number of black asci characters to somethign that would engage the script to tell it to send the "select" command. I guess it may or may not work in that instance. If it's off, then you'll get a black image, and the script will tell the channel changing command to send a power on first, then send the channel change command. Just my 2 cents. My situation is for a SA3250HD with Time Warner Cable in Milwaukee, WI using a ir blaster and s-video into my PVR-350. I like it this way also because I can record HBO and all channels I subscribe to. I don't too much care that they aren't in HD. I can record an HD channel but obviously since it's sent over s-video it gets downconverted I am guessing. All my shows look fine to me.
