OK. So you have the IR receiver connected to the PVR card, and the
transmitter connected to a serial port?

OK. Here's where it might be going wrong. How many instances of LIRC
are you running? If its only 1, and you're using lirc_dev and
lirc_i2c, then only the Hauppauge hardware is being using used which
means it can't send.

What you need to do is configure a second instance of LIRC to driver
the serial based transmitter. Full instructions are here:
I am now running a receiver/transmitter device running off one serial
port (I took a working receiver and transmitter and soldered them into
the same shell. This made is somewhat simpler for LIRC as the single
instance of LIRC when compiled with send support can with receive and
send IR signals.
