Apparently, the bundled IR receiver module does not work with 3.3 volt supply. So, the Hauppauge guys chose to drop the 5 volts from the PCI bus by R47 (49.9 ohms) to something like 4.1 volts, so that the cheap IR receiver will still work and not kill the I/O pin on the cx23882.
Next step for me is to get a 3.3 volt capable IR receiver and connect my hardware to the 3.3Vaux and PME# lines on the PCI bus.
Do you know any drop-in replacement modules? I've always though the bundled one had too low sensitivity as well.
I added some pictures of the Everlight IRM-3638N3 to my web page: http://www.iki.fi/~msmakela/electronics/worc5/#ir
