When that happened on a weak signal of mine, I just hit channel up and within 10 seconds the channel changed. I then blocked the weak channel. No lockup or reboot.

At no point in your rambling, incoherent post were you even close to anything that could be considered a rational thought. Everyone in this forum is now dumber for having read it.

Last week we heard from an experienced technician who proposed that there are two or more issues causing reboots. I agree. My set is a single issue apparently, has had reboots but never a freeze and does not care about the quality of the station's signal. It will attempt to tune in stations with zero signal strength and not reboot or cause any problem. I could not discern a pattern of any kind to reboots except that most occurred in the morning hours.

My set has not rebooted in four days, a record. It is operating, I dare say, perfectly. The only change which took the DVR from reboot death spiral to faultless operation was marrying it to the television by plugging both into the same receptacle which is not controlled by a wall switch. To repeat, the DVR and television are now plugged into the same three port adapter which in turn is plugged into a single receptacle. This strongly indicates that rf noise was the source of the original problem. The noise might be coming from the antenna amplifier or some other source, I don't know and may never know. Somehow, the television is protecting the DVR from this problem, maybe through a common mode effect or some other mechanism which is grounding out the problem noise. I know this is wild guesswork but one thing is clear, changing the location of the power plug made an immediate and possibly lasting effect to the good.

The poster who suggested that a ferrite be experimentally applied to the coax is thinking along the same lines as me. I will be looking at doing some of these things as soon as the chokes are received. As it stands now I don't need to but that is not what it is about.

How did your machine act on the 5th, 6th, 7th, & 8th pass over the "problem" spot?

I received a replacement unit on 2/3. It reboots on average about 1-2 times a day but I've not yet had it freeze up. It has never gone more than a couple of days without a reboot.

I'm undecided whether to try for a third unit. I wonder if they are just rebagging the returns and sending them back out. I don't see how they can be repairing them since they don't know what the problem is. Since the problem is random, it would probably pass any of their factory tests. I doubt that the replacements are new units since they ship alone without the accessories. I worry that I'll get a worse unit than I already have.

So it seems that the replacement units are subject to the same "some work well, some don't" scenario we have seen with the original purchases.

Signal strength is about the same as before on all channels but PBS is now fixed since it's no longer right next to the CW anymore. I had some adjacent channel issues prior to the switchover.

I actually did to a complete rescan and still got the 70-1 instead of 9-1. Therefore, I then did a factory reset, partly because I heard others now getting the TVGOS after a factory reset. However, after the complete rescan again, it's still calling it 70-1. So I don't know what's going on with it. It doesn't seem to cause any problems other than a different name for the channel. I did a rescan on my actual TV too and it still calls it 9.1 so it's something the DTVPal DVR is doing to change that channel number.

I'm still not seeing TVGOS either. I just think my CBS affiliate isn't broadcasting it. I can't get them to respond to emails either.

I found the Radio Shack ferrite Snap Choke Core EMI/RFI filters (Model 273-069) that have been discussed at my local bricks and mortar store. Cost was $2.99 plus tax for a pack of 2. I had printed out a page from Radio Shack's website to hand to the clerk at RS which was good because they had them hidden in a drawer of miscellaneous parts. So my plan is to install one on the power cord and one on the coax coming in to the unit. Also I will burn some incense as a previous poster advised and chant "RFI begone! RFI begone!" several times to bring good karma to the installation. Also I will do a factory reset.

I'm already over 90 on most my stations so strength isn't a concern.

I am noticing that PSIP data that I only get seems to be populating a little better. Also, for some reason one of my channels has changed it's number. It use to be 009-01 and now it is 070-01. Strange.

Just curious what others may be seeing who have markets that made the switch.

Of the two stations in my DMA that switched. One, the local CW station, is displaying a static image (I.E. If you are seeing this, your set is not ready for digital....bla...bla), the other, the local FOX station, is running a looping bilingual video about how to set up a converter box.

As far as my DVR...nothing different that I can see.

I'm wondering if the software is dumping corrupted information to the drive. I really want to pull the drive and run spinrite on it to rule out any hardware issues, but don't want to ruin my warranty if there is a major recall. Reboots do seem to be coming closer together now, sometimes 4-5 in one 1/2 hour show.
Anyone else seeing reboots triggered at the same point in a recording?

My machine does the opposite. It never reboots when I go over the same spot where it rebooted before. I regularly go 2 weeks without a reboot, and then I'll get 2 reboots when watching a one hour show. After rebooting I back up a minute or so before the reboot spot to check for some kind of stream corruption. I never see anything (other than what I'm supposed to see )

Feature Request:
Have future models include a Coaxial Audio Out aka SP/DIF.

I can't understand why manufacturers don't include Coaxial Audio out (SP/DIF) for digital audio out. It's electrically IDENTICAL to Optical out (TOSlink). All they have to do is stick a RCA jack on the back and wire it to the same place on the board as the Optical connection. I can't tell you how many devices I've had to hack for this! Optical does not SPLIT nicely, the signal levels plummete horribly. So for those of us with limited numbers of digital inputs on their receivers, or a LOT of devices with digital audio (I currently have SIX digital audio devices!), coaxial digital is GREAT because you can split it with a 50 cent splitter, and as long as the "competing" devices are switched off via macros when you change sources with something like a harmony, there is no loss! No downside! I only have 1 coaxial audio input on my receiver, but I'm running 4 devices off it and it works great! Other receivers friends have had (lower end devices) ONLY have coaxial audio in! It's an easy as heck hack most of the time to add a coax audio out, so the manufacturers really should be doing this..

Oh well, another theory shot down lol.

One thing that seems to help me is after the reboots get annoying (multiple in an hour) I will do a factory reset, rescan my channels and all is relatively fine for a few days (minimal reboots). Now I don't know if this is just because there are no timers set, or not.....I'm sooooo confussssssssed!

What's not to be happy about. Other than a few bugs with the way it handles NULL guide data (I.e. it doesn't remove the previous shows description when the current show is null) I've had no problems. My reboot count is still at zero after resetting it at the beginning of January.

I feel for you guys having problems and I would have probably given up by now if I was having the same issues.

I am currently using a Winegard SquareShooter SS-2000 amplified antenna. I have had this well over a year and it works great. I thought this may be a good source of interference as well. Has anyone thought about trying a ferrite on the coax into the box?

So far, I have had no reboots today even while recording multiple shows simultaneously and watching a 3rd. I had been getting several re-boots prior to this.

Here is my theory. There are many sources of noise in digital circuits. Almost all devices that use digital logic have clock generators that are used to shift data through registers. These clock generators typically are very noisy creating what is sometimes called grass because of how it looks on an oscilloscope. They are very fast rise time spikes. This noise is radiated if the device does not have good filtering and shielding. Now what happens to other devices in the area (like the DTVPal DVR) is the power cord (or other cables that have parallel conductors) act like an antenna and pick up the spikes (RFI). These spikes if not filtered out can get through the power supply and ride on the logic voltage and trigger gates and registers when they are not supposed to be. This can cause the processor to reboot because of an illegal event.
The power cord is the most susceptible to picking up the RFI because it is not shielded. Coax, like the antenna or audio and video cables are less susceptible because they are shielded. Also Ethernet cable is UTP (unshielded twisted pair) and is what is called balanced. Noise picked up on the UTP conductors is canceled because of the twisted balanced pair. So typically you don't need to put a RFI filter choke on Ethernet cable. Now it may be helpful to put it on HDMI cable if your using cheap HDMI cable that is not shielded.
Anyway I counted twenty three digital devices in my house, from microwave oven to two PCs, VCRs, DVD players, TV monitors, and even clock radios. It's now been ten days since I choked my DTV Pal DVR power cord and no reboots. I had previously been getting between 1-3 reboots per day. I'm not saying this is the absolute cause of reboots, there may be many. But so far it is working for me.

Are you willing to run the experiement of taking off the choke (without unplugging the device) and seeing if the reboots return?

Along with this, here's a short thread in another forum that talks about the "prodigious RF" emitted by Panasonic plasma TVs... don't even have to be in same room! May be of interest to some?

Yes. I do plan to take it off to see if the reboots come back. But I was going to wait until next week. This week the weather has been fairly mild in my neck of the woods. I want to go through a storm first to see if that has any affect. This weekend it is supposed to get nasty.

Also, if my theory is correct about the power cord acting as an antenna for the RFI, just moving the cord may have an affect (like moving your rabbit ears). So I don't want to touch it for another week. Then the fun begins.

You guys that have had success by plugging it in to another location may have just found the "sweet spot" where there is minimal reception of bad stuff. If my experiment works out, "choking" the power cord will be a "sweet" fix.

The DTVPal DVR does have an EMI filter. You can see the inductor and capacitors that make up this filter in pictures of the circuit board. The job of this filter is to keep the significant RF noise generated by the switching power supply from getting onto the power line. It of course works the other way as well.

I think what may be happening is that all these devices that are emitting RFI noise are not synchronous. So sometimes the several spikes will occur simultaneously and be additive. So I think the effects will not be predictable and occur random-like. Also I think external factors from outside the home would be minimal. The RFI radiation decreases by the square of the distance and were not talking about huge signals. It may get picked up by house wiring though.

As a bystander (and a consumer of electronic goods) I think that none of this should be a factor in an electronic device that is properly designed, has quality parts, and is properly assembled and tested BEFORE being offered to the consumer.

I did a rescan on my actual TV too and it still calls it 9.1 so it's something the DTVPal DVR is doing to change that channel number.

I'm still not seeing TVGOS either. I just think my CBS affiliate isn't broadcasting it. I can't get them to respond to emails either.

Are you in the OKC market? If so KWTV doesn't broadcast TVGOS data to the best of my knowledge.

I agree. I still think it has something to do with PSIP\\TVGOS and, or reception.
Mine logged a reboot overnight while in standbye, during a severe thunderstorm -
very heavy rain and high wind. It was the first reboot logged in weeks,
the last time being during an ice storm.
Edit: Of course the storms could have caused fluxuations in the power too.

I can't understand why manufacturers don't include Coaxial Audio out (SP/DIF) for digital audio out. It's electrically IDENTICAL to Optical out (TOSlink). All they have to do is stick a RCA jack on the back and wire it to the same place on the board as the Optical connection. I can't tell you how many devices I've had to hack for this! Optical does not SPLIT nicely, the signal levels plummete horribly. So for those of us with limited numbers of digital inputs on their receivers, or a LOT of devices with digital audio (I currently have SIX digital audio devices!), coaxial digital is GREAT because you can split it with a 50 cent splitter, and as long as the "competing" devices are switched off via macros when you change sources with something like a harmony, there is no loss! No downside! I only have 1 coaxial audio input on my receiver, but I'm running 4 devices off it and it works great! Other receivers friends have had (lower end devices) ONLY have coaxial audio in! It's an easy as heck hack most of the time to add a coax audio out, so the manufacturers really should be doing this..

I too wish more devices had both types of outputs. My Denon has 2 of each type of input, I'm running my CD player through the analog inputs, DVD and DTVpal use the optical. TV uses the SP/DIF output, my other SP/DIF is unused.

Called tech support today concerning reboots. I had a number of reboots when I first got the unit. They first suggested plugging it straight into the wall. That seemed to have fixed the problem until 2 nights ago when the unit rebooted 6 times in 3 hours. Last night was fine.

The tech said that they are very aware of the issue and are confident the next software release should fix the problem. I guess we'll all just wait and see!

And no..... No ETA on the release.

These clock generators typically are very noisy creating what is sometimes called grass because of how it looks on an oscilloscope. They are very fast rise time spikes. This noise is radiated if the device does not have good filtering and shielding. Now what happens to other devices in the area (like the DTVPal DVR) is the power cord (or other cables that have parallel conductors) act like an antenna and pick up the spikes (RFI). These spikes if not filtered out can get through the power supply and ride on the logic voltage and trigger gates and registers when they are not supposed to be. This can cause the processor to reboot because of an illegal event.
The power cord is the most susceptible to picking up the RFI because it is not shielded. Coax, like the antenna or audio and video cables are less susceptible because they are shielded. Also Ethernet cable is UTP (unshielded twisted pair) and is what is called balanced. Noise picked up on the UTP conductors is canceled because of the twisted balanced pair. So typically you don't need to put a RFI filter choke on Ethernet cable. Now it may be helpful to put it on HDMI cable if your using cheap HDMI cable that is not shielded.
Anyway I counted twenty three digital devices in my house, from microwave oven to two PCs, VCRs, DVD players, TV monitors, and even clock radios. It's now been ten days since I choked my DTV Pal DVR power cord and no reboots. I had previously been getting between 1-3 reboots per day. I'm not saying this is the absolute cause of reboots, there may be many. But so far it is working for me.

Keep in mind also the house wiring is basically and extension cord to the DTVpal's power cord. All RFI picked up by the house wiring is sent down the DTVpal's power cord. My Monster surge protector is supposed to have RFI suppression but I'm not sure how effective it is.

Hopefully the inability to set a manual M-F timer will be addressed also. The odd thing is mine used to work until I had to rescan the channels for the DTV switchover, now I just get an error message when trying to set a M-F timer.

Measurement of rfi could be done with the right equipment and an experienced operator. I guess the power line could be checked with a coupler and an oscilloscope. The air could be scanned with a field strength meter and scope. It would be tricky and might not yield much because the problems appear to be intermittant. One nitpick about the statement:

Quote:


The RFI radiation decreases by the square of the distance and were not talking about huge signals. It may get picked up by house wiring though

Power decreases by the inverse square but it is the amplitude of the field which causes the problem. Field strength is related to the inverse square root of the distance. For example, at twice the distance the field is determined through dividing by the square root of 2. Far field only.
