I just set my Direct DVR on the ledge below the TV, stays put. There is only the two of us, no kids running around to knock it off. The 29RL TV is next to the hallway to the bedroom & can be easily bumped. I have thought about some type of more permanent mount or larger shelf area fastened below the TV, since the OEM shelf is rather narrow & leaves a lot to be desired, but have not as yet. Are you using regular signal or HD DVR, there is a trick to aligning dish quickly with HD. Basically do not connect HD DVR to dish until signal is obtained from sat finder or LNB may go into Maint mode & not synch up. I can go into more detail if you want on the dish setup, not sure if this is the place.
