Yup, it will work fine. I have two switches between one of my HDHRs and the router, and I have no problems at all.

Hi,

Has anyone here built a script to collect and save all the Signal strengths, signal quality and so on for all their stations and save the results to a file?

TIA

I have.

I used AutoIt for what I'd call a "brute force" method of recording the data. It's not pretty and it's designed specifically for the channels in my area but it did the trick.
post #1834 of 1962
The hdhomerun_config command line will scan every channel and report what type of signal it is, what the strength and quality are, and what programs are in the stream, and can optionally save to a file.
Code:
hdhomerun_config ffffffff scan /tuner0 filename.txt

This is good stuff.

I notice in a document on SiliconDust's website (http://www.silicondust.com/hdhomerun...evelopment.pdf)
that more information can be gotten by executing

hdhomerun_config get /tuner/debug

Most of the resulting output is explained, except for the 'dbg' entry. Does anyone know what that is? For the example given in the document: dbg=22081-6930. When I run the command on my unit, I get: dbg=13696-11234-1314.

Dbg are the raw signal numbers coming from the tuner. Revision 1 devices use the 2 number format, while revision 2 are 3 numbers. The numbers aren't particularly useful for anything except internal debugging.

Ive got 2 HDHR's on my network, latest sw on the XP box. l sometimes get the capture, and the Tray Icon goes away OK, but the HDHR keeps streaming to the PC like it didn't hear it's time to quit. I can clear the issue by starting four Quick Viewer windows and selecting a channel in each.

Ideas ?

Thanks Much,

I did..... haven't got a response yet. I've gotten a lot of help here @ AVS, so I thought I'd give both a try.

Thanks for Your Suggestion Though,
post #1841 of 1962
Chris--

Are you talking about failure to stop after CW_EPG captures? If so, the issue is likely with that sw rather than HDHR's. I suggest that you pursue it in the CW_EPG thread.

I changed the record buffers, waiting to see if that helps. Odd though, you can watch the tray icon terminate like it should, but the HDHR just keeps streaming......but this don't always happen....sometimes it works like it should. Beginning to think I have network problems, as I think I might be getting dropouts in 'recorded programs' if 'heavy Net surfing' at the same time. I'm using GB switches and PC ports, but the last time I checked my throughput to a FreeNAS box, (perhaps limited to the 550Mhz CPU) I got right at 100mb....guess I should start there.

This just started out of the blue, can't think of anything I've changed. Can't remember the first time it happened....just recently. Did update CW to 4.0, then to 4.0.1 to fix the SD/Time Warner bug.....????? hummmm

Thanks TP
post #1843 of 1962
Chris, you can use the HDHomerun_setup.exe with /debug to get a diagnostic showing any LAN dropouts. I've forgotten the syntax, but I expect you can find the instructions on the SiDust site (or maybe Jason can post a refresher here off the top of his head).

One potential bad actor in this regard is ZoneAlarm, which--in the past, at least--definitely caused lost packets on HDHR captures.

only thing I could find was a debug mode used to send a support ticket...I'll try that to see if I can generate a viewable log file.

Using Comodo FW, it doesn't even look at the HDHR stream, but do a TiVo transfer, and it uses 30% CPU resources scanning every packet....Go Figure.

Thanks,

You may want to run multiple copies to test multiple tuners at the same time.
post #1846 of 1962
Thanks, Jason, that's exactly the test that I had in mind.

Chris, please give it a shot.

Your problem is not wall warts. Your problem is LOW QUALITY
products.

I used to dislike wall warts, until I read about the problems
people were having with the internal power supply on the Roku
Photobridge. I then realised that having the frequently
problematic power supply be a seperate device that is easily
replaceable and easily upgradable if necessary is actually
a good thing.

I don't know why power supplies are so frequently problematic.
A power supply isn't rocket science. Once you get a good design,
keep using it. The devices being powered are new and different,
so I'd expect that would be where the problems appear.

> With USB3.0 offering higher power output, I'm hoping that

With USB, the device is supposed to tell the host how much power
it needs. The ability to do this will make the device more expensive,
and is one more thing that can fail.

Which would make the power strips more expensive. And what makes
you think that these power strips with USB would be of any higher
quality than the wall warts you are currently having problems with?

Read the label to find the specs you need (5 VDC 2 Amps or whatever)
and then find a decent quality power supply that can meet those specs.

I've been wondering about the quality of the power these things put out,
and if this would hurt reception. Sounds like it is worth looking into.
Thanks.

Hi everyone,

I know that you can't mix ATSC and QAM signals using Vista's Media Center, but can you do it with SageTV on a Vista box?

Or am I stuck upgrading to Windows 7, which I'm hesitant to do because my HTPC has pretty anemic specs (AMD Athlon 64 X2 2.2GHz, 1GB RAM, Sapphire Radeon HD5450 512MB DDR2, 160GB HD)?

Thanks in advance for your feedback!
post #1851 of 1962
I've been pleasantly surprised how well an older machine runs Win7. The threshold is definitely 1GB of RAM, so you're good there. More would be nice, of course, if your motherboard supports it. Same thing with the dual-core AMD. I'd expect Win7 to run slightly faster than Vista on it, but not such much as you'd really notice.
post #1852 of 1962
Thanks for the reply, Bill! I'm going with upgrading to Win7 so we'll see how this old box handles it.

I was planning to add more RAM but with Vista and the Radeon 5450, but VLC didn't even max out the 1GB installed when I played an mkv rip of The Pacific as a test. I'll have to play it by ear, obviously. Thanks again for your help!
post #1853 of 1962
The one thing to watch out for with Win7 is how ATI screwed up the drivers. If you depend upon unusual screen resolutions that aren't supported via EDID from the monitor then it *might* take some fiddling. Win7 does a more robust job of detecting monitors, which is great if your equipment is compliant. But if it's not or like me you're using a KVM switch then it takes a few steps to disable the autodetection. NVidia drivers do not have this problem. Their driver is smart enough to allow you to choose the settings you like and not interfere. ATI *really* screwed up with this.

But if you've kept up with ATI's drivers then you've probably already run into this trouble on Vista too.

Regardless I would still encourage you to give Win7 a try for all of the other good things it has to offer.
post #1854 of 1962
Yeah, after finally properly setting up the HDHR and WMC in Win7 for my indoor antenna and clearQAM, I now have the pleasure of figuring out how to get rid of the 1" black borders all around the output from my HTPC on my tv and the annoying white noise coming from my speakers before the ATI HDMI audio drivers load upon startup... sigh.

At least the Jets are winning

Thanks again for your advice, Bill
post #1855 of 1962
I just finished setting up a dual HDHomerun unit on my network to record ATSC content to my HTPC.

I was fiddling with the QuickTV software and found something interesting about it.

My HTPC outputs digital audio over optical (from a PCI soundcard with optical digital audio output), which sends digital audio to my lowly Logitech Z-5450 speaker system.

Normally, when I tune in to TV with the HTPC, the audio is a Dolby Digital stream, which can be either 2.0 or 5.1, depending on particular content.

For example, when I tune in to the show "Smallville" on my local CW station, this program has Dolby Digital 2.0, which plays in stereo mode on the Z-5450. (All audio comes from front L/R speakers only.) So I thought that is how this program's audio was encoded (Dolby Digital 2.0 stereo, that is).

But when I tuned in to "Smallville" using QuickTV, the Z-5450 played the program in Dolby Pro-Logic II mode, so there was dialog in the center speaker, and music on front L,C,R speakers, and some ambient sounds on the rear L/R speakers. I liked this presentation better.

So my question would be, how do I find out what QuickTV is using as a Dolby Digital decoder in my HTPC system? Because MyHD, VLC, and TheaterTek all play "Smallville" in stereo mode. Thanks in advance.

Would AC3Filter provide that information?

Isn't Dolby Pro-Logic II a way of converting stereo to pseudo surround audio? I thought that this is only done by your receiver when it gets a stereo source. Therefore, it may be that QuickTV is sending out stereo, whereas your other players are sending out two channel (or 2.1) AC3. Anyway, what I think is happening is on your receiver and not so much on your PC. QuickTV is apparently sending out lower quality audio and your receiver is applying its Dolby Pro-Logic II processing to it.

Thanks Hyrax. Some additional information...

- When the Z-5450 receives DD 5.1 over optical, it decodes and plays back in 5.1. It does not seem to allow switching to other surround modes or processing.

- When the Z-5450 receives DD 2-channel stereo over optical, it decodes and plays back in 2.0 stereo. It does not seem to allow switching to other surround modes or processing.

- When the Z-5450 receives DD Pro-Logic encoded 2-channel over optical, it decodes and plays back in 4.1 surround. It does not seem to allow switching to other surround modes or processing.

- When the Z-5450 receives 16-bit uncompressed digital audio (i.e. from a CD), it can switch between three "Effects" options: Music Mode, Movie Mode, and one other mode I can't remember ATM.

Since all my HTPC software players send unprocessed audio from ATSC sources (which are all Dolby Digital), they can't be changed by the Z-5450. But I think the QuickTV software is pre-processing the audio signal - somehow changing it from 2.0 stereo to 4.1 surround - before sending it out to the optical. So I am wondering what audio decoder (in my system) is used by QuickTV that would do such pre-processing.
