As far as the ORDER of the channels in the guide, yes, there is no order. Not only that (again referring to the 3410A --- I don't have the Sony), some cable channels do not even appear in the guide, while others appear that I don't have. This happens notwithstanding the fact that the guide is "customized" to your zip code.
You can tune the channels that don't appear in the guide, but of course you lack the info and recording setup features for such channels.
It wouldn't be so bad rearranging the order if you just had to do it once. But the LG will, at random times, reset the order and the remapped channels. What a pain! I'm hoping the Sony has improved on this.
This type of box seems to have two possible sets of problems: the manufacturer's hardware/firmware, and the TV Guide. Troubleshooting becomes difficult when the line between these is not clear. I would think that the Sony hardware/firmware would tend to be reliable, and that most problems will be caused by the guide.
I suppose you'll see what happens over the next couple of days. I'm sure many of us are curious about the Sony, and are waiting to see how it acts.
Oh, boy, I wonder how long it will take THIS thread to match the 3410A's 130+ pages?!?
