Cannot change channels beyond 125 with Composite 1
I have searched hard for an answer to my problem and I have seen a few posts but no solutions. If there is a link somewhere that explains the solution please reply with it so I can follow. Ok, my problem is that I'm running Mythdora 4.0 using Schedules direct for guide data (which works great). I have a single Hauppauge PVR-150 in my mythbox. My television service is DirecTV which I'm using with Composite 1. I would think with this kind of configuration that myth wouldn't default to the 125 channel limitation of the "tuner" itself since I'm using the composite but I cannot go beyond 125 channels. If I select a channel beyond 125 sometimes I just get blank guide info or it will reset back to channel 70. I can change the channels fine with anything from 2 - 125. I must have something configured wrong but I do not know what. I have tried playing with the "frequency" in the general settings of mythsetup to no avail. I have tried US-Cable, US-Broadcast etc. I wouldn't think it would matter since I'm NOT using the tuner, just the composite in. Any input at all would be GREATLY appreciated since I'm sitting here scratching my head on this one. Please let me know if you need any additional details about my configuration.
Thanks in advance!
