I am currently using a DirecTV receiver, without a serial port, that has the IR connector. The IR is very slow and doesn't change the channel correctly a lot of times. I have gone through the various settings several times and this doesn't help. The Pioneer DVR-810H-s TiVo can't even change the channel to record it correctly. I guess I have been spoiled by the DirecTV/TiVo combo.

I would like to use a DirecTV receiver with a serail port, so can someone please recommend the DirecTV receivers with serial ports to use with the Pioneer DVR-810H-S.

And is the serial port more realiable than using IR with SA's?
