Recorded Presidents Cup from Golf Channel HD today. Started viewing recording. About 1:30hr into recording, started getting GC program from another time - could not fast forward, skip, pause what was being shown. Hit Info button and showed still in recorded program, but was not. If I STOP playback, goes to live broadcast of GC. Also, for first time, have started getting DU1 on front of DVR when switching between HD and SD channels. Have never had this before 1.7. Am using Sony Bravia tv with HDMI cable.
