HDHomeRun - Dual ATSC or QAM to Ethernet Box - Page 5

Nothing has been posted in the MCE-Beta forum at SiliconDust yet.

Will this device work with the new game consoles like X360 or PS3? Turning those into DVRs?

Theoretically I believe you could use it with a PS3 with Linux installed on it.

That seems very interesting. Has anyone been able to install Mythtv on the PS3 linux OS. If you can install Mythtv then it would not be difficult getting this tuner to work.

Also since you can install a larger HDD in the PS3, you would be able to use the PS3 as a HD-DVR.

See, now THAT would get me to buy a PS3 for the price they are asking. Unfortunately, it would NOT convince my wife to let me.

When I first saw the PS3 spec, I was thinking it's missing a tuner! Now this might be the answer. Interesting.

I just installed one of these on my Sage system. I was using a direct connection rather than through a router, and setting that part up was a PITA (DCHP or whatever). But once that was done, the rest was a breeze, and it seems to fully integrate my QAM and OTA HD channels into one lineup!

Only a few hours of it running, so my opinion may change, but so far, but for the networking issues, it's been really nice.

Hi Karyk,

Are you running any sagetv clients on Laptops or other pcs?

I'm interested to know the performance for placeshifting using this Hdhr.

No, I'm not.

Here's the link to the thread on it in the Sage Forums.

Unfortunately, the first three pages are so are all just speculation of what it will be like when it is released, but you might find your answer there.

A couple of reviews on the HDHomeRun.

HDHomeRun: Record OTA HD Programs without Installing a Tuner Card: DVR playground

Can the HDHR run with both inputs connected to OTA ATSC sources and selectively map the channels to the inputs?

This question is peculiar to me. Where I live, all the OTA broadcast sources are in two groups set 90 degrees apart. Rather than use a rotor, I'd be happy to put an HDHR in the attic, point two antennas correctly and forget about it.

I'm close enough to the signals that, for the moment, I can use a Silver Sensor indoors and just use our Daniel rotor system.

That's going to depend on your software. I think you could do that through Sage, but I'm not sure. I know you don't have to setup (and if QAM remap) the channels for the second tuner in Sage, but I don't think there's anything keeping you from doing that. Since you can have one tuner OTA and one QAM, I'd guess you can do what you want with both OTA.

I've tried many, many combinations of wireless connection properties in an attempt to reduce or eliminate picture breakup. I've been experiencing picture breakup for around 3 seconds every 10 to 20 seconds.

I'm using a Dell E1505 notebook running Windows Vista and a Dell 1500 802.11a/b/g/n wireless card. I don't believe this issue or fix is particular to this card. It may effect other cards supporting 802.11a. This issue also effects 802.11g performance using the same wireless mini-PCI card so it's not a 802.11n issue.

The fix greatly reduces the breakup duration from 2 to 3 seconds to a split second. The number of breakups doesn't seem to be reduced, only the duration of the breakup.

The fix is to change the property named "Disabled Bands" from "None" to "802.11a". This disables 802.11a on the wireless adapter.

The difference is significant in that wireless viewing is now mostly good. Remaining questions are:
1. Why does changing this property makes any difference?
2. What is causing the data rate dips?
3. Does this effect all applications or only HDHomeRun or only UDP?

I will move to another location next week which should clarify whether this is an interference issue.

You can see the improvement caused by the property change by viewing the two attached jpegs. The important difference is the depth and duration of signal loss as shown by the two Windows Task Manager network connection graphs.

The developer suggests the occasional wireless breakup *might* be due to the wireless connection occasionally re-searching accesspoints. This would explain why disabling 802.11a improves the connection. Does anyone know if this happens on Windows and how to disable it? This explanation seems consistent with my observations.

I've looked through the registry and tried various network options but can't find anything that helps.

Check you router options, only select the connection type you are using on your wireless adapter. It has been documented that "mixed" data rates "a", 'b", "g","n" can slow throughput on wireless connections. So if you are only using "g" select the option in your router to support "g" only.

Router is set to connect at 802.11n only.

This is not a bandwidth issue as the connection uses no more 10% of the available bandwidth of 130mps.

I'm using Dell Wireless 1500 802.11n miniPCI adapter on Windows Vista. Router is a Netgear WNR854T.

Vista driver issue? (new OS teething pains?)


Mixing manufacturers incompatability issue ?


draft n issues? (non formalized spec teething pains? ... mixing manufacturers with pre n spec equipment issue? )

Bob,

What is the MTU on your LAN or the network adapter on your Dell Wireless? Are you runnning it at 1500? Try 1496 or lower like 1372.

CityK, those are all possible sources of the problem. I may be able to eliminate each theory -- eventually.

leonowski, I don't see MTU property on either the adapter settings or router.

The MTU setting is changed on the IP level. You should be able to query the MTU of all adapters in vista using this command:

netsh interface ipv4 show subinterfaces

(Run the command prompt window as an "Administrator" or this command may not work)

After the query, look for the interface that refers to your wireless connection. It may still read as "Local Area Connection." Type this command to set the MTU:

netsh interface ipv4 set subinterface "Local Area Connection" mtu=1496 store=persistent

Then, do the query again to verify the change.

The MTU is the "Maximum Transmission Unit"

http://en.wikipedia.org/wiki/Maximum_transmission_unit

leonowski, I changed mtu on my wireless connection to various other settings such as 1200, 1492, 1496, 1500 (default), 1550. The show command verified the change. However, none of the values seemed to make any difference in the frequency or duration of the breakups.

Thank you for leaving detailed instructions. It made it very easy to try out the idea.

I'm personally eagerly awaiting when this will be usable with MCE (more specifically, Vista MCE). Until then though, I'm sticking with my MyHD 130.

Due to the complete lack of information about MCE development, I am seriously beginning to wonder if it will ever happen. Don't get me wrong (I have already ordered one), but I think it will be a huge task to overcome MCE's restrictions on tuners/epg. I joined the SiliconDust's MCE usergroup and NOTHING has been posted yet. SageTV support was started and finished in just 2-3 weeks, and we haven't even seen a post yet. Believe me, I DO hope they prove me wrong.......

I received my HDHomeRun last week, which I ordered in anticipation of MCE support. While a progress report would be nice, there have been near-daily firmware and driver updates, so it may be that the developer(s) is/are cleaning up the driver before completing MCE support, which makes sense. Most companies take forever to write functional software, but SiliconDust is working quite rapidly. It's unrealistic to expect significant software development to take only a few days. I'll be very happy when MCE support arrives. VideoLAN sucks (big-time) for HD viewing on a monitor, and doesn't record. Last I checked, there weren't a lot of members in the MCE Usergroup on the SiliconDust Forum. If more MCE users would sign up, SiliconDust would take that as an indication of interest in MCE support.

I'm definitely interested in MCE support. I'd buy one (or two) as soon as drivers appear.

They've posted three updates to the Sage software in the past 7 days, so perhaps they are trying to get the other software products fixed (and I'm using a four generation old product without issue) before moving to MCE. They can probably only develop for so many things at a time.

Try the free trial of SageTV while you're waiting.

Since SAGE supported the idea of a network tuning device long before this device appeared, the rapid SAGE development is a no-brainer.... adding it to MCE might be VERY problamatic....

Indeed, same thing for the official BTV support, they pretty much have to start from scratch.

If this thing supported multicast... You could hook 2 of them up to the network, tune your 4 major networks, and any HTPC on the net could grab one of the multicast channels...
