missing recordings, must I leave cable box on???  

post #1 of 14
Thread Starter 
Hey team

It looks like when I turn the cable box off, RePlay doesn't know how to turn it on to record the shows I want.

Must i leave the cable box on all the time???

This seems stupid. If the IR blaster can change channels, why can't it turn the cable box on and off when required.

Please help a newbie out.

thanks, Wade

YES, YOU MUST ALWAYS LEAVE THE CABLE/SATALITE BOX ON.

Many/most home electronic devices do not have seperate ON and OFF codes/signals.

The Replay assumes that the connected device is ALWAYS on and can only opperate in this way.

Leave your cable box on 24/7 as stated in your ReplayTV manual.

The ReplayTV has no way of knowing whether the cable box is on or off. Since the command to turn it on or off is the same command that works as a toggle, if the ReplayTV assumed the box was off, when it was already on, sending the command would turn the box off.

Just leave the cable box on. There's no good reason to turn it off anyway.

On page 29 of the manual:

Although ReplayTV does not need to be on to record television,
your cable box and/or satellite receiver must remain on.

Alright, someone has to say it...

I said I was a newbie!

anyway consider the following.

Yes the on/off signal is the same, but I don't buy that the RePlayTV has no way of knowing if the box is on or off.

All it has to do is check for a video and/or audio signal. If there is none, than assume the cable box is off and thus send the on/off signal and check again. If there is a signal then the box is on.

You would think that a $300+ box would have simple logic.

So DUH!!!, maybe you typed too soon!

It does have simple logic. It assumes you read the manual and have the cable box "on" all the time.

Many cable boxes still output video when off, so the simple solution is to leave them on.

Since you are a newbie, let me strongly suggest that you purchase a 350-500va UPS and plug both your Replay and Cable Box into it. This will ensure that your system will survive any power bumps that otherwise might get things out of sync, as well as protect the Replay's always spinning drive.

Simple logic just doesn't cut it. Some cable boxes leave a video signal ON when they are off, they just send black. So, in some cases, that wouldn't work. Also the Replay doesn't know if the cable box is directly connected to it or goes through some other componant. (Which is a valid setup). What if you ran it trough another device that fooled the Replay into thinking that the box was on...

Also, if there was a glitch with the on/off routine, you would miss recordings. It seem vastly better to leave it on than to turn it on and off with the Replay, to me.

I think the programmers looked at all of the problems involved with cycling the box and decided it just wasn't worth it. (Plus you have no power savings, so why bother)

He's probably new to Replay, but not to the AV Forum in general. That would be my guess. Just because someone has numerous posts in a Home Theater forum, or HDTV forum or whatever, that doesn't make them an expert on Replay. Personally I didn't think it was that stupid of a question. Why not just answer the question without the sarcasm??

maybe it's because i'm trying to be nicer to people...but this really doesn't strike me as that dumb of a question...the whole send power signal if no video/audio is an idea that i had a few years ago (as have many other people)...but once you've used replay (or tivo) for a while i think you realize it's so much easier just to leave the box on and not have something else to worry about

having said that...you really should split your cable so you can use the replay's internal tuner to record the shows from basic cable...then you don't have to worry about the cable box most of the time

Forgive me for seeking help on subjects I have little knowledge about.

I thought that was what this forum was about. It has help me so much during the construction of my HT. Generally when some types "Newbie"
it means "I don't know what I'm talking or asking about" so that those who
do will be kind enough to share some answer and point the lost person in the correct direction.

someone asks for help and others take turns to telling him how stupid he is, what gives???

To all of the productive posts, thanks!!!!!

Now to my defense.

I did read the manual. Like all of us who get new stuff, I was more interested in getting the thing working than reading the manual in detail.

I did read the part about, the cable box had to be on in order to record but the RePlayTV did not. The set up required inputting the cablebox device # to get the remote codes. You confirm that you had the correct codes by turning the cable box on/off with the ReplayTV.

So I incorrectly assumed that the RePlayTV would turn on the cablebox before recording.


Simple logic ...
Yes I knew that some devices send and audio signal through the optical cable when off, however I didn't know some devices also send a black video signal. Good points all around.

One simple viewpoint.
It just seems to me that all devices should have a power down sleep mode like computers and or away of networking with other devices, which would not required any device in the network to remain full on 24/7.

Forgive me for being a newbie to replayTV even though I've been a member on this forum for over a year with 200+ post (smile )

oh I'm sorry, I should know better :) instead of (smile).

people here are sometimes a little harsh.

Not only do some cable boxes send a black signal when off, some actually continue to tune the last channel while off. My cable box does this (GI CFT2200 w/ cablevision). So the other day when a fuse blew in my apartment and I forgot to turn the cablebox back on, I got ESPN for everything that was supposed to record the following day. Imagine my surprise when I went to watch the West Wing and saw sportscenter :(

That is why the latest round of automated AV switches work differently that the prior models. In the older models tended to be the type that switched to the active signal (many times ignoring new active signals if the old signal was still present) However, they soon realized that too many devices send signals when they are off, so the new designs now switch to the video signal that came on last or as signals go off will switch back to any active signals present. This makes life much easier as those switches work SOOO much better now.
