Unsure if this is a GT or WMC issue.


You can add any missing channels that Media Center doesn't add during an auto scan. Go to Settings->TV->Guide->Add Missing Channels->Add QAM Channel-> Enter the Channel Number (if you don't know the channel number you can get the digital channel number using the OnAir software (the list of channels in the Channel Manager) use the correct channel number for the missing channel (IE: Channel Manager Listing = 16.1 WBOC DT is one of the available channels for me so 16.1 is the channel # you'd select) Media Center will then ask you if it is QAM 64 or QAM 256....Most of the ones in my area are 256 so that might be a safe bet for you to try as well. Then you will have to name the channel...this is totally up to you you can name it anything you want. Then click add. Now all that is left to do is map the correct EPG Listing to that Channel and you're done!...Hope that helps ya

Thanks for the tip -- took me a bit to realize that the physical channel was listed in the the "Edit CH" dialog from the Channel Manager since all my channels were showing up by the virtual channel. Had to walk the physical channel as it doesn't tell you whether WHDH is 85.1, 85.2, etc. By the way, you don't have to guess at QAM 64 or QAM 256 as that's also shown in the channel edit dialog as well.

The next time I plug them in to use them with Media Center it's like Media Center is seeing both of them as 1 tuner and I can only watch or record 1 program at a time. If the tuner setup wasn't so time consuming I wouldn't mind going through the setup each time I want to use both tuners but it would become a pain, and since my notebook doubles as my HTPC leaving both GTs plugged in isn't really an option for me.

My question is, is this a Media Center error, or could it be an issue where the driver needs to clearly label the 2 GT tuners (IE: ONAIR1 and ONAIR2) in the device manager so that Media Center can tell the difference between the 2 tuners? Any help or suggestions on this would be greatly appreciated.

By the way the beta driver works flawlessly with a single GT tuner with Windows 7 RC 32 Bit Media Center!

FWIW, I had this problem in WinXP with a fast machine. I refer to it as a race condition. The second instance needs to see that another instance is already running to get properly created. At first I merely separated them in the start up list and that worked for a while, but it is an unreliable solution. I then started using a startup delay progam from r2 studios http://www.r2.com.au/ without further issues. I do not know whether they've created a Win7 version yet.

So basically Media Center needs to be using 1 of the tuners before I connect the 2nd one so that it can tell that there are actually 2 tuners installed? If that's the case it's not too big of a deal. As far as a startup delay program I have absolutely no idea how to use it. I'll try watching a program on 1 tuner and plugging in the 2nd to see if that gets me going with dual tuners. Please correct me if I am misunderstanding what you are saying. I dabble in tech but I am far from being a pro at this stuff. Thanks for your help!
post #2735 of 2955
Also just to note the Onair GT TV program works fine with both tuners, it is only Media Center that has the issues after reconnecting the 2 tuners.

I tried this and didn't have any luck with it, going to play around with a startup delay program and see if that gets things up and running. Any guidance with the startup delay prog. would be helpful. Thanks!

If you can figure out how to load the necessaries by a DOS-like command,you can use a batch file (.BAT or .CMD) called from the Startup folder. A line like this between the commands for the two devices can insert delays (just change the "3" to make them longer):

ping 127.0.0.1 -n 3

Here is an example of how it can be used to clear the Print Spooler in case a print job gets stuck in the queue:

net stop spooler
ping 127.0.0.1 -n 3
del %systemroot%\\system32\\spool\\printers\\*.* /F /Q /S
ping 127.0.0.1 -n 3
net start spooler

I'm not a media center nor Win7 user, so I'm relating my experience of running two OnAir Creators on a single system using their scheduler/capture programs. At startup time only, when the OnAir schedulers are first loaded, two copies need to be running; the second loaded sees the first and then knows to open the second schedule. If both get loaded before either is in control, neither sees the other and they both open schedule 1. This may be the same kind of situation you're seeing with Win7 MC. If it is, it would almost seem mandatory that you connect one after the other is recognized. I've no idea how to ask MC to delay between calls to opening the devices.

Your description of the problem sounds very much like an MC problem. When you first setup MC it worked properly with both tuners. Afterward, when you launch MC, whether or not both tuners are connected, it will only recognize one tuner. A startup delay will not help.

If OnAir's TV program is working properly (and if OnAir's scheduler is also working properly?) that sounds to me like a better solution than MC.

Just an update on my 2 tuner issue. I originally thought that I was having this issue after disconnecting the tuners from my laptop. Further testing showed that this happens as soon as Media Center is restarted. I have tried testing using both Windows 7 RC Media Center, and Windows Vista w/TV Pack 2008 and I get the same results with both. Interestingly the setup takes about half the amount of time to complete in Windows 7 as it does in Vista Media Center. Hopefully the next Beta will address this issue, but I can handle setting up the tuners each time I need to use 2 in the meantime.

I installed the latest beta driver build, and was impressed with glitch free operation. Everything worked great in Win7MC (just 1 tuner). ClearQAM let me set up my entire cable lineup.

HD viewing was studder-free, smooth and in sync. I'm impressed since my test computer for Win7 is only an XP2500+/1GB/GeForce6200(256MB)

Ryan, I sent a more detailed report to the address you requested.

Is anyone running the GT on an Intel Atom CPU?
Thinking of building a micro system for a simple cheap hi-def DVR using the GT and Atom CPU. Playback isn't critical as I have PopcornHour and Egreat media devices for that task.
Thanks... Rob

There is still an issue when using two Autumn WaveGT tuners and Win7 x64 RTM. I have reported this issue and they are looking into it now.
post #2744 of 2955
Yeah I just tested the 2 OnAirGT tuner issue on the 32 bit RTM last night and saw that the issue still exists. I also reported the issue when I was running the RC but I haven't heard anything yet, so here's to hoping that this is fixed in the next beta driver.
post #2745 of 2955
Does anyone know why my onairgt does not work after I installed vista sp1. I also upgraded my Nvidia 8500gt at the same time to it's latest driver and now nothing works. I previously had the latest hardware drivers and software for the onairgt and have reinstalled them again after the vista and nvidia updates to no avail. The onair application opens but will not move off the "file" choice,can't choose digital or analog or get any other function.
This is why I should never update a system onceit works well!!!
thank you,
Joe

Does the GT show up in the device manager? If it does, check the properties to see if it says if the device is working properly. Next question did you install the driver with the GT plugged in? If not that could be your problem and you may need to reinstall the driver. Also while installing the driver on Vista be sure to Click "install this driver anyway" when it warns you that the driver isn't signed. If you are still having issues you may want to test your USB ports using another USB device, and test your GT on another PC if you have one available for testing. But most likely it's a driver issue that's causing you headaches.

thanks for the quick reply. It does show up in the device mgr but not working. Even unistalling ane manually installing the drivers doesn't help. I have tested the usb ports, even use a powered usb hub as the onairgt is finiky about power. It worked fine before sp1 and nvidia drivers. just checking to see if Ryan or others have had the same problem and what the fix might be. Maybe I'll just bite the bullet and get a Media Center capable tuner instead. I am pretty impressed with MC since I set up my daughters college computer two weeks ago, way improved since I looked at it yers ago.

Go to device manager, uninstall the GT tuner and check the box to remove the drivers. Then unplug the usb cable to the tuner. next uninstall the the gt software. Now update windows to SP2. Next go to the nvidia website and install the latest video driver. Then install the onair GT driver v3.02. Now plug in the GT tuner you should see it install in windows and it should show up in device manager. Next go to windows media center and under tasks set up the tv signal for your area. Once the setup is complete you will be able to watch tv from media center. You dont need the the gt tuner program but if you also want to use it you can then install it to watch Outside of Media center if you wish.

Please keep in mind that if he doesn't have TV Pack installed and the beta drivers for the GT, the Media Center solution may not be a good one if you are looking to use the GT for clearQAM cable.

I have done this at least a couple of times now and still get an error. Ryan, do you know why I am having this problem becuase all it says is to contact the manufacturer?

Just to let anybody know, I went back tp the 3202 (previous driver) and everything works fine now. Ryan, why would that be?

I have been using 2 OnAir GTs for 2 years now without any video quality issues. But now I am getting dropped video and audio frames somewhat frequently. I have tried using a powered usb hub to insure that the GTs are getting the proper amount of power, and this has helped but I'm still getting the errors. I also use Videoredo to edit the commercials out and convert the files from ts to either mpg or dvr-ms depending on what I want to do with the file. Here is the summary from one of my Videoredo edits (this one isn't as bad as most but I cleared the log because it was so big):

Mode: Frame Accurate
-Video output packets: 2695941
-Audio output packets: 204484
-Padding output packets: 0
Video output frames: 220621
Audio output frames: 115022
Processing time (secs): 519
Processed frames/sec: 424.30
Actual Video Bitrate: 11.83 Mbps
* Input Sequence Errors: 9
* Video resync frames removed: 32

Does anyone have any idea on how to improve this. When I first started using the GT and videoredo I never got errors like this. I usually use the record stealth option, and when I check the system performance using the task manager CPU usage is usually at 35% or lower, and memory usage is usually lower than 768MB with two GTs recording at the same time. I don't know if it's the signal quality ,an issue with the GTs, or a PC issue. Here are my computer stats:

HP Pavilion dv6226us
320GB 5400RPM HDD
2GB DDR2 RAM
Intel Pentium Dual Core 1.6GHz processor
Intel 945GM Graphics w/128MB dedicated
Generic Powered USB 2.0 Hub
Windows 7 Enterprise

Any help on this, as always, would be greatly appreciated!
post #2754 of 2955
I would check the simple, mechanical things first. Has the Coax cable come loose or is it worn? What about other connections/splitters, are they all tight? Are you getting your connection from Comcast or OTA? If Comcast, they are known to have signal quality issues that crop up. Check your signal strength.

Did you installed any new software/hardware on your system when the problem started? That could be keeping the system from servicing the GT data, resulting in lost frames?

post #2755 of 2955
Yes I have checked all my connections, the coaxial cables are in good shape, tight connections and high quality cables and splitter. Very minimal software installed, and nothing new since the problem has started. My signal strength on the Onair program is between 33 and 34.50. I do use Comcast cable and I know they have issues at times with signal quality so I think that may be my issue. Thanks for your help, I just wasn't sure if I was missing anything in my troubleshooting.
post #2756 of 2955
Ryan, any word on when the Windows 7 64-bit driver will have a final and/or signed version? Figured I'd ask since it's been a couple of months since the beta was out and I was wondeirng if there's any updates (if you can talk about them .
post #2757 of 2955
Dunno what I've done now but for the last few weeks my OnAir GT display pauses and starts/stops on all channels. (Vista 64, user account, clear QAM cable)

Is this a known problem with a fix? It didn't used to do this.

Power problem? Some degredation of the USB power it's getting?

Probably not. I previously bought a powered USB hub in case it would help with other GT problems. But it doesn't seem to make any difference here.

post #2760 of 2955
Only issue I've had so far (just started to notice recently) is after a sleep/hibernate the OnAir sometimes doesn't detect a signal. Unplugging and plugging fixes it.
