HDHomerun channel scan 1.4.7

[Shoey Peachew]

I'm fustrated with all PC TV card tuners in general and I'm almost to the point where I don't want to deal with them anymore. Why can't we just plug the card in, install the software and click a couple buttons and setup is complete? Why does it have to be so time consuming? I'm not accusing anyone here as I've used a number of different software and devices and it's all the same problem solving over and over again.

Anyway, I installed the latest HDHomerun and GBPVR and did a channel scan. I noticed when the scan completes, the "Digital Channels found during scan" leaves much to be desired. As you can see in the pic I provided below, I've changed the Guide Names in the HDHomeRun Setup to match the channel names from the Zap2it website. However, the digital channels found in GBPVR's config don't match up with HDHomeRun's setup like it used to in v1.3.11. So, even though some channel names match, most channels come up as unknown or unmatched, which leaves me the task of figuring out which channel to map to. I just wanted to point this out and maybe make it function as it did in 1.3.11 to save some time setting things up.

When you change the names in the HDHomeRun channel editor, the changes are not immediately reflected on the SiliconDust Lineup server where GBPVR gets its information. It can take a day or two for the Lineup server to get updated. You can check the Silicondust website to see if your updates have been published. You did however just make scanning and mapping easier for the next person in your neighborhood that does it.

Neither the names you see in HDHomeRun setup, or the names you see on the zap2it.com website are available in the stream, so GB-PVR has no way to know these names. The names you see in GB-PVR are what the broadcaster is transmitting.

The reality is that the FCC chose to make channel names optional in digital cable streams, and the majority of cable companies dont transmit any names. Because of this you typically see names in tv apps like 'unknown' etc for the majority, the same as you see in GB-PVR. You typically only get real names for rebroadcast ATSC channels.

The only difference in the 1.4.7 release is the option at the end of a QAM scan to try to determine the channel names using the internet. When you choose this, it goes over the internet to SiliconDust website to ask for the names, which if you choose this should give the same names you see in the HDHomeRun app.

If you decline this option, you'll be left with exactly the same results as you were seeing in 1.3.11. If you seeing anything different, then its likely the broadcaster has changed something about the stream.

I should have been more clear. I made these changes in HDHR's channel editor months ago and my channel lineup was already published at Silicondust's website. When I uninstalled/reinstalled HDHR to the latest version today, I entered my zip during setup and HDHR automagically updated the channels names for me. Also, I used to use Other:ATSC/Remap with v 1.3.11, but this setting doesn't seem to work with v1.4.7 and I'm forced to use GB-PVR as the Main Application in HDHR's setup. I suspect this may be part of the reason I'm having problems.

Yes, this would be the cause of any difference. When the HDHomeRun does this ATSC/Remap, it inserts its names into the stream, which is why GB-PVR will show its names. When the HDHomeRun sends the raw stream (not its modified ATSC/Remap stream), then its back to the names the broadcaster includes in the stream, which usually means no names ("Unknown" channels).

I'm not aware of anything that has changed in GB-PVR 1.4.7 that is forcing you to use GB-PVR as the main application vs the ATSC/Remap option you've used in the past.

Did you try the option to improve the channel names over the internet? With any luck this will get you the same HDHomeRun names.

After scanning in GBPVR, do you get a popup asking for your zip code? If not, delete your scan cache files (backup first of course) and try rescanning. After you enter your zip code in the popup, the channel names on the right should change from "Unknown" to what is on the Silicondust lineup server. When you select the channel in the dropdown, scroll all the way to the bottom for the renamed entries.

I'm still working on the new QAM setup guide to outline all this, sorry.

As for not being able to use ATSC/Remap, I don't know why you can't use it. GBPVR would just see it as an ATSC tuner instead of a QAM tuner. I'll test it if you remind me on Sunday.

Ok, I'm a little confused since the HDHR setup plucked the correct names off of Silicon's website, but when I checked the website the names were different. Maybe I just need to wait for it to update again or something. Either way I'll get them mapped, it'll just take longer.

Yes I did get the popup. During my trial and error run I tried entering and not entering my zip code. Entering my zip code provided some of the channels names, but not all of them. I'm going to try ATSC/Remap again.

The HDHR setup would have retrieved the names from your Digital Cable.xml and overridden what it got from the website.

Ok, thx for the help, but it's getting late and I'm going to put it to rest for now.
