[mythtv-users] RCA DirecTV DVR -- DVR40

[kirk]

I'm having some problems getting my RCA DVR40 directv/tivo receiver to
change channels using any of the scripts <a
href="http://tarek.2y.net/myth/">here</a>.  The receiver has a mini
serial port on the back (1/8" phono -- stereo???).  First off, does
anybody know if this port is actually enabled on the receiver?  I've
done some searching but cannot find anything myth related to this
receiver :(

Is anybody else using a RCA DVR40 direcTV/Tivo receiver?

My backend is a Barton 2500+ on a Leadtek K7NCR18G Pro II motherboard,
512Mb PC3200 RAM, 2x250Gb WD, PNY GeForce4MX 440, Hauppage PVR250.

This backend is also used as a frontend.  I also have a XBOX frontend
running Xebian.  The XBOX frontend launches from EVOX, and looks great!
(better than the GF4 too).  I have the DVD remote for the XBOX and it
works fine -- except that it doesn't change the channel!!!

I've checked <a

Any ideas?  Thanks!
