There is still a serious bug on my 622/722's....
When I watch a program on my external drive, then press stop when I'm done, and then start watching a second show off the external drive, then press stop, the title screen that comes up is the screen for the first show. Not a major headache, until I realized that when it did this it deleted the second program and the drive available space increased. It was especially annoying if I pressed stop to go watch dinner halfway through a show and the show was now gone.
I found a workaround..... If you change the channel to a different channel midway through (ie. turn to 200 and CNN) then the bug doesn't strike.
But I'm surprised more people aren't running into this... Maybe people are just archiving shows and not viewing them off the drive as often, and if they are doing that, they aren't watching a second show.
BTW, if you go on to watch a 3rd, 4th, 5th, program, etc. the bug doesn't show up. It ONLY strikes on the second program.
