I have 3 THR22's, I'm experiencing blank recordings, just black screens for the entire duration of a recording. One program will record fine on that channel, the next program will be blank. It's entirely random. I'm wondering if it might be related to showcase downloads that take over channels (though I've never figured out why those don't use the internet connection). I've also got swivel search working on one receiver, but not the other two. I've force software downloads, and run all the Hard Drive, antenna, and network diagnostics with no sign of trouble. I read on DBSTalk that others were reporting the same problems. I've also noted some inconsistencies in the THR22 from the SD Tivo's. When I cleaned the To Do list on the SD units I could manually select a program to record at a later time, and the SD unit would automatically remove the duplicate earlier recording. With the THR22 I have to manually remove the duplicate.
