Is there anything to indicate that there actually a separate IR receiver on the board? Most cx231xx devices have an MCEUSB compliant IR RX/TX built into the chip, and thus they don't use a separate part. Also, IIRC, address 0x30 is the I2C address of the onboard analog frontend for the cx23102, and I suspect you're just reading the values out of the AFE. I suspect you've grabbed a dump from the initial device plug-in, which would coincide with the initial register programming of the AFE. I suspect if you connect the device, let it device settle, *then* start the I2C capture and hit a key on the remote, you'll see traffic on a totally different endpoint which would be the IR traffic being sent back over the IR interface/endpoint.
