Re: [mythtv-users] Changing channels on DCT2000 series/audio questions
Thanks for the link! I found a few things: 1.) I was, in fact, changing the channel on my cable box (serial cable was going from my mthtv box to the Motorola STB- I just didn't see the numbers changing). This seems to be all set. 2.) Regardless, I don't seem to be getting any cable coming into the PVR-250. I'm beginning to wonder if perhaps the hardware is screwed, since I only seem to get channel 4, and changing the channel, while effective on the cable box, does not show any change in channel in MythTV. Also, I seem to be getting nothing but white noise unless the coax cable is jiggled out some. Could this be an ivtv thing, not interpreting the cable signal correctly? Or is it more likely to be hardware-related? 3.) I put the .asoundrc in the mythtv home directory, and when I logged back in to see if it worked, it froze my X session. It didn't go through the rest of the startup, and I had to kill my X session. Is there any way to see why this happened? Thanks so much for your help so far, guys!

Re: [mythtv-users] Changing channels on DCT2000 series/audio questions
Actually I meant to look at the LED display on the DCT2000 and see whathappens. Ah! Yeah, stupid me. I actually watched the cable box and didn't see anything happen, so what you're saying about an inactive serial port is entirely possible. I'll have to call them up and ask about it. Thanks! I don't suppose you have any thoughts about the sound, do you?Peace! ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Sorry if I'm > being thick about this. And thanks for the suggestion! Actually I meant to look at the LED display on the DCT2000 and see what happens. However, you could definitely try running the channel script while watching livetv from within mythtv. If neither of those show a change, then it is possible that the serial port on the DCT2000 is disabled. You can try asking your cable company to enable it, but they might say no. Mine did, so I'm stuck with IR blasters. Mark ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Changing channels on DCT2000 series/audio questions
Have you tried using the change channel script directly. As in/usr/bin/channel 24 Well, so far all I've done is done /usr/bin/channel 5from the shell while MythTV was not running. When I ran mythfrontend and watched LIVE tv, I didn't see any difference. Do you mean I should run MythTV, then try running the command from a shell outside? Sorry if I'm being thick about this. And thanks for the suggestion! ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
