[mythtv-users] Hauppauge IR Receiver

[MythTV User]

I purchased a Hauppauge PVR-250 on e-bay and it came with the remote, 
but not the IR Receiver (despite the fact that the guy who sold it to 
me claimed he was shipping everything that originally came in the 
package).
Anyone have any information on how I can build or buy one that plugs 
into the PVR-250?  I would rather do that than use a serial port 
version since I only have one RS232 port.
Thanks
