I am glad you could resolve your problem. I am having a very similar problem with the PVR-150 MCE kit I bought a week ago. I have not been able to make the remote work, so I was very interested in your post. Does anyone know if the PVR-500 remote/receiver is the same as the PVR-150?
One thing I could not understand and maybe some of the more technically versed in lirc folks around this forum could maybe clarify. If the current version of lirc included with LMCE is 0.8.2 released June 9 per the lirc website, which apparently does not support the IR receiver bundled with the Hauppauge MCE kits, as documented in several threads in this LMCE forum and my own experience, how come Mitsus was able to get his remote working with version 0.8.2pre2 which was apparently released even earlier (April 26).
I am not questioning that Mitsus remote is in fact working and I am very happy for him having shared the knowledge. It seems to me that at least in theory, everything that was included in lirc 0.8.2pre2 should be in the official lirc 0.8.2 release. Am I misunderstanding something?
