I have an HR44 which was provided to replace an HR34 that was acting up. One of my TVs has a C31 client which periodically freezes during fast forwarding. It seems to happen most often when fast forwarding at X2 speed, but I have also seen it occasionally at other speeds. I have had no problems with the set attached to the HR44. For other reasons, both the HR44 and C31 have been reset since the HR44 was replaced, so that does not seem to fix the problem. Before I call DTV and maybe ask for a C41 to replace the C31, I wanted to see if others are having this problem, and if those of you with HR44 and C41 are not seeing the problem. I also have an HR20, an HR22, and two H25s, but I have had that setup all along so I don't think they have anything to do with the HR44 and C31 issue.
