How do you change between firewire and S-video? I would love to differentiate between the two and be able to get the channels that I can't receive over firewire all through the same box.<br><br>Thanks<br><br><div><span class="gmail_quote">

I did a little bit of testing with this last night and had moderate,<br>but not complete success. As far as i can tell, at the moment I have<br>no choice but to try to implement something like this on channel<br>change. Why are you hesitant of doing this Jim? I have not
<br>experimented much with broadcast, but what i did seemed to be<br>consistent failures... and even if it worked that would not impact the<br>issue below would it?<br><br>I am running a single SA3250HD and using both the firewire out for the
<br>available HD channels and the s-video out for some non-HD digital<br>channels. Quite often when switching from one of the channels being<br>fed from s-video back to firewire the firewire stream is lost. The<br>channel is changed correctly almost everytime, but the STB will not
<br>enable streaming (as if the new channel is 5C) In the past it seemed<br>the only way to resume the connection was to unplug and replug the<br>firewire cable from the cable box. What i noticed last night was that<br>
some but not all of my available HD channels would work as the first<br>HD channel when using the sure_change script. For example....<br><br>301 - HBO non HD fed over s-video<br>1421 - ABC HD over firewire<br>1460 - TNT HD over firewire
<br><br>Start on 301 -> Change to 1421 (Stream is lost)<br>Start on 301 -> Change to 1460 (Works)<br>Start on 301 -> Change to 1460 (Works) -> Change to 1421 (Works)<br><br>I have no idea what would be causing this behavior. Any thoughts? Or
<br>things I can try? My only other thought was to add into the channel<br>change script to change to 1460 automatically if the stream is not<br>successful, retest, and then if 1460 is working change back to the<br>intended channel. Obviously this is not an ideal situation, but i
<br>figure i can at least give it a try to determine if the behavior i was<br>seeing last night is actually consistent.<br><br><br><br>On 11/20/06, Yeechang Lee <<a href="mailto:ylee@pobox.com">ylee@pobox.com</a>> wrote:
