No, that doesn't make any sense (re: Remote battery dies). To trigger bulb mode with an IR remote, I would presume that it is:
1. one button press - shutter opens and stays open until...
2. next button press - shutter closes...
For it to work this way, it would have to be a different IR pattern that the K20D recognizes (at least that is how other camera IR remotes work).
I would be very surprised if the Pentax Remote F keeps sending an IR signal for as long as you want the camera shutter to stay open.
If Bulb mode works on the Pentax Remote F, it must send a different signal (that is not available on the Chinese remote). Otherwise, the shutter would close if you stop pointing the Pentax Remote F toward the camera.
Please correct me if I am wrong (I have never used the Pentax remote).
