In a nutshell, some owners have had failure of the timer recordings. I would be less concerned with the "padding" failure because that has to do with the TVG system. If you read all the threads, there appears to be a problem for some, regardless of manufacture. The problem that some have experienced is that they have missed recordings when the system was set up to manually record. Could this be to to the internal clock being messed up by the TVG??? maybe, maybe not....no one know why this happened. Correct me if I am wrong, but people who have the TVG working perfectly have had no problems, and people like me , who don't use it, have had no problems(I can't recieve the datat because my cable company doesn't carry the channel that provides the data).
I personally thing that the biggest problem with this unit is there is no way to conpletely disable the TVG system....it is too integral to the unit operation.
