Hi I'm Trying to record tv from comcast through a set top box. I know i need an ir blaster but before i buy one such as a remote ir blaster combo or just an ir blaster,
Id like to know how it will set up.
I think you're confusing an IR Blaster with an IR Receiver. The IR Receiver is required if you intend to use a remote control or media center type keyboard. This just allows you to control the tuner card software (either native Hauppauge software or Windows MCE).
The IR Blaster provides the ability or over-run a third party's device such as a set top box using a remote control or media center type keyboard.
In my previous set up, I had the following devices and a Comcast Set Top box:
The IR Receiver connected to my PC via USB. The IR Blaster cables actually connected to the rear of the IR Receiver. (One of these allows me to use the Microsoft Remote Control to control the Comcast set top box).
Looking at the Hauppauge 1250, it looks like it has an IR Receiver, but no additional IR Blaster cables. The IR receiver (black cable with grey headers in the last image) connects to IR input of the TV Tuner Card. It doesn't look like there is a way for you to control your Comcast Set Top Box using that receiver.
If you do get an IR Receiver/Remote Control combo (like the one I linked above), you would probably use that instead of the included IR Receiver, but I have no idea if it would actually work.
I'm pretty sure that all three remotes are going to work exactly the same. It was a different brand name, but I actually had that Hauppauge style remote control. It worked well enough.
My main concern though is whether or not any of them would work with your TV Tuner Card. I assume they would, but can't say for sure. With your card (or at least the Hauppauge 1250), the IR Receiver actually connects to the TV Tuner card. All of these IR Receivers connect via a USB port on the computer.
I'd definitely do more research before plunking down any money. At the very least, try to get in contact with Hauppauge and ask them.
Huh... Well, if this is your card, then I don't see anything like an IR Input port on it, so it would have to be a USB connected IR Receiver.
What Hauppauge products can be used with Vista's Media Center application, which comes with Vista Home Premium and Ultimate?
The Hauppauge TV receivers are certified for use with Vista's media Center application:
Any model WinTV-PVR-150, WinTV-PVR-500 or WinTV-PVR-USB2
Any model WinTV-HVR-950, WinTV-HVR-1250, WinTV-HVR-1500, WinTV-HVR-1600, WinTV-HVR-1800 and WinTV-HVR-1950.
For Europe, any version of WinTV-HVR-900, WinTV-HVR-1100, WinTV-HVR-1200, WinTV-HVR-1300, WinTV-HVR-1400, WinTV-HVR-1700 and WinTV-HVR-2200.
Since the card you have looks exactly like the WinTV-HVR-1250, let's assume that it what it actually is. While this section states Vista, it should also work for Windows 7.
How do I configure my Microsoft IR Blaster remote control?
Connect the IR "beanbag" to an open USB port on your PC. The drivers should automatically load. Check your device manager for a "Human Interface Devices" listing, which should contain: HID-Compliant consumer control device, HID-Compliant device (3 instances), and Microsoft eHome Infrared Transceiver. If the device does not get detected or fails to install, try a different USB port(s) on the PC or refer directly to Microsoft. Also try installing Microsoft's "Rollup Update 2"
This tells me that it should work with any of the devices you linked previously.
