I have a Sharp 42" 1080p TV that I bought used for the 1/4 of new price. Directv receiver is a HR-24.

Great TV. However the issue is not the TV.

My Hitachi 1080p set (that I returned today for several bad pixels), was able to display a 1080p VOD fine, and when I checked the 1080p box in the menu of the D* box, it would work.

Not the case with this TV.

Directv however is not wanting to take any blame and pointing at the TV.

I have a samsung blu ray player, connected to another HDMI input, when I watch a blu ray, the TV pops up with a box in the corner that says INPUT 5-1080p.

So this TV is a 1080p set (which the maker said), and can display 1080p content fine.

I also switched around the HDMI cables, did not make any diff.

So the problem is that this HR24 is not wanting to handshake correctly with a 1080p signal.

What could be causing this?
 
While you may be right, you're assumption that the HR24 isn't handshaking correctly may not be true. Your bluray player could be doing it wrong...

I have a Panasonic plasma and my HR24 does fine with 1080p. And so did your Hitachi.

So the issue could be the Sharp is being way too picky about the handshake...
 
1. Don't rule out the TV. Certain models of Sharp's, and other brands, in the past have had handshaking issues. There is an Edid table that is used to communicate between devices. Samsung Blu-ray players are able to "force" 1080p/24 even if the table is not quite correct. My Panasonic BD player, on the other hand does not force 1080p/24. neither of my HR24's have any issues with 1080p VOD.

Best you can do is try switching inputs for the devices. Also check over at AVS in the thread for your particular TV and see if anyone else is/has had problems with 1080p material.

Found the issue. Only newer HDTVs that support 24 frames per second video (1080p/24), will accept 1080p from the Directv Receiver. The blu-ray player is 1080p/60fps and will work.

So basically Directv is saying if you own a older 1080p set, "No 1080p for you!"
 
Now I wonder if a blu ray recorder will allow 1080p to pass through as 1080p/60. I dunno if a switch like that could change frame rates.
 
Now I am wondering what fps the 1080p from directv is, because my TV has Film mode, which states.
[FONT=Arial, Helvetica]Film Mode: when set to On the film mode automatically detects, analyzes, and converts a film source (24 fps) to video (30 fps) using 3-2 Pull-down[/FONT]

I turned this on and no luck.
 
You mentioned in a previous quote, the 1080p had to be on Input 5, could it be that this input is the only one that will handle what your trying to do ?

If your BR is on this input the D* recvr can't ?

Not sure, just thinking.
 
If the TV has it, try turning off HDMI-CEC (AquosLINK). That's just one more thing that could interfere with the handshake.
 
Here are all the facts I can give.
The model of the TV is a Sharp Aquos LC-42D62U Made In November of 2006.
It has 2 HDMI Inputs.

There is a FILM MODE in the video menu, that's supposed to take 24fp and convert it to 30fp.

However this film mode does not function in any progressive format like 720p or 1080p, it's not needed.

From what I understand Directv outputs all its 1080p ppv's and Vod's to 24fp

Even with film mode on, it still wont work.
 
Did some more looking.
Looks like it will scale from 24fp to 30fp ONLY when the 24fp is delivered in a 1080p/60fp signal. It will not accept a 1080p/24fp signal. Sounds confusing but it is what it is.

Seems 24fp is new technology and not supported by older HDTVs.

One of the hazards of buying a five year old TV. A couple of the manufacturers (including Sony if I remember correctly) didn't support 24fps until more recently on even their XBR series.
 
Not new. Film has been 24p since the dawn of time. TV standards were and continue to be 30fps. Since home media has taken a stronghold in households, TV's have started accepting and displaying film in its native format. What the "old" film mode actually does is supposedly smooting out motion judder inherint in films shot at 24 fps and being displayed at 60fps. It has no affect on TV shows.

I love wallowing the in the fantasy of DIRECTV forums. Custom "facts" (hogwash) are hatched at an alarming rate by posters using matter-of-factly tone.

24fps for film didn't become a standard until 1930 when getting talkies to sound right became an imperative. Frame rates varied from 14fps to 26fps and were determined more by the technology of the day than the visual aspect. The need to avoid burning the film if it spent too much time in the projector was a major driver for running the film speed up while keeping the projectionists happy meant moving the film moving slower so there weren't so many reels to handle.

It is also noteworthy that each frame is flashed more than once when projected. Thomas Edison determined that the minimum flash rate was about 46 flashes/second to avoid eye strain. Modern projectors flash each frame three times (72 flashes/second) before they move on to the next.

Frame rate - Wikipedia, the free encyclopedia

As for TV standards, there are several acceptable progressive video frame rates including 24fps, 30fps and 60fps.
 
There's a difference between capture and display. As of 2011, there are currently three main frame rate standards in the TV and movie-making business: 24p, 25p, and 30p. Film is captured at 24fps, 3:2 pulldown can be applied to convert it to 60, or the frame can be repeated in multiples of 24. Video is captured at 30 fps and can be displayed either interlaced or progressive. 60p is common in set top boxes, BD player outputs (not inputs), and home video, i.e. camcorders. Tv shows, not live, that are captured on film are usually 24fps and converted to broadcast standards by applying 3:2 pulldown.

Going back to the OP, his TV does not accept the format that D* and E* broadcast for their film based VOD, which is 1080p/24.

If your TV only supports 1080p/60, then it won't support the DirecTV 1080p/24 signal. But it does not matter. because movies are filmed at 24fps, that's all the data there is. That means that 1080i, 1080p/24 and 1080p/60 all have the same information content, the additional frames are created by duplicating the frames that already exist. That means that if you set your DVR to 1080i, and watch a 1080p movie, the picture quality will be the same as if your TV did support 1080p/24, unless your TV has a very poor de-interlacer. Just try it and see.

That's what I used to do with my old Sharp Aquos that didn't support 24. It looked great. I now have a Sony that supports 24 so I am able to use the 1080p setting.
