Here's an interesting problem that seemed to develop yesterday, as it has never happened before (I have the latest software for the 500 model, which is 10AF, correct?). Upon calling up my VOD menu, I selected a program to view, but it would not play. The screen went black. I waited a minute or so, then I exited the program, but the system went into the guide menu, and would not let me exit back to viewing live tv full screen. I put the unit into standby, then switched back on. Still unable to exit the guide menu. I pulled the power for 30 seconds, then everything seemed to work fine for the rest of the evening. I was able to play the pre-rec'd episode with no problem. I woke up this morning and tried to call up another program that recorded overnight...same problem. Black screen, sluggishness, etc. Rather than pulling the power, I just pressed reset this time, and all seemed to be okay; I was able to play the episode in question. However, after it was over and I went back to watching live tv, I was unable to pause or rewind. The status bar seemed to indicate that the show was not "streaming" from the drive as the indicator never gave me the orange proress bar. Had to pull the power again. I am trying to patient with this R15, but just when I think it is beginning to get the kinks worked out, some new wrinkle develops. I think it can be a great unit...but my wife says she has just about had enough. (Any other husbands with this problem? We're willing to stick with it, but the Wife is building a head of steam that threatens to blow any day now?) I truly wonder where DirecTV can go from here. If they continue to have problems well into the year, is there any way that they will come forward, admit the unit is defective and offer some kind of replacement? I like the R15, and want it to work, but on the other hand I don't want to get stuck with a defective receiver, either. Software revisions can only go so far, and if these revisions fail to put the device to rights, then someone is going to have to start asking questions about the hardware as well. ...Just wanted to add another remark or two. I know this post is getting lengthy.... Everyone on this forum seems to have some amount of tech savvy, and so these problems, while annoying, also are...interesting. I can only imagine the frustration of someone who is not technically inclined. Calling tech support day after day and resolving nothing. Perhaps it's only my imagination, but I think I can also sense a sort of helpless despair in the voices of the tech support people I have spoken to. It's pretty rough for DirecTV to put them on the front line like this, having to bear the brunt of everyone's anger and frustration with a device that just doesn't function as it should.
