Jerky Video and DVD codec.

Well i still have no luck. Updated my PowerDVD 5.0 which the widows dvd check
program said it was good to go. Still jerky as hell. I tried nVidia DVD
decoder and still no luck. By the way when I did my clean install I also
installed rollup2 and video was perfect. It was only after installing Nero
that things went bad.
I guess I will have to do another clean install.

Hi guys,

Im writing another post, this one is to do with our MCE2005.

The original, working installation became unstable after nearly 2 years so I
thought Id try putting on Vista instead, that didnt work (see my other
thread) and so I thought I would start a fresh copy of MCE2005 and work on
Vista another time.

Ive got everything exactly the same as the old MCE2005 but the picture isnt
smooth, its continuous and doesnt break up but the picture doesnt flow
smoothly, its sticky, the best way to describe it is if youre watching a news
ticker scroll along the bottom, its not smooth, it jumps across the screen.
This is the same for recorded TV and live TV but NOT for DVD's, they play
fine.

Please can someone help, Im on the verge of a nervous breakdown, Ive spent 3
weeks doing this in total as well as missing all my TV!

Thanks.


Ross

If you use your tuner card manufacturers TV application software instead of
MCE how is live and recorded TV?
Have you checked to be sure you have the latest MCEdrivers installed from
the tuner card manufacturers Website?

Based on your other replies I am not sure this is the cause but the
information may still be of help.

I currently run my Media Center 2005 on a computer LCD screen (not a TV
screen). This LCD supports refresh rates of 60Hz and 75Hz. In the US, TV
runs at 60Hz so if the LCD was set to 60Hz as well it would be a perfect
match, however here in the UK/Europe TV runs at 50Hz. The LCD initially
defaulted to 60Hz and this resulted in a very bad jerkiness of the image
when showing things like stock/news tickers scrolling across the bottom of a
live news channel. This is because the difference between 50Hz and 60Hz
cannot easily be compensated for by an even number of frames. When I changed
the LCD to 75Hz which is 1.5 times the TV rate, this made it much easier for
it to compensate and the jerkiness was significantly reduced (but not
eliminated totally). I hope that if/when I change to using an LCD TV as the
display (which will then run at 50Hz) that the problem will completely go
away.

In theory, I would expect a computer LCD able to run at 100Hz would be as
good as one that can run at 50Hz in this situation.

As I said, I am not sure this applies to you but the background may be
helpful.

Other than that, merely installing a certified codec is often not enough,
indeed I found that even setting it as preferred was not enough and I had to
go further and set the directshow filter priority so it was the highest
priority (while the MCE codec utility showed it was set as preferred, when I
tested playing a recording using graphedit it still showed a different codec
being defaulted to, once I changed the directshow filter priority level,
then it did default to the desired codec).

AFAIK an LCD display (computer or TV) refreshes its screen out of a full
screen buffer at its refresh rate setting. This activity is independent of
the refresh rate output of your graphics card. When the display receives the
updates from your graphics card it just refills the buffer with it.
Running the display at a faster refresh rate does insure that it is more
likely to get the latest update from your graphics card. There are now some
LCD HDTV available in the states that refresh the screen at 180Hz even
though their HDTV program input is as low as 30 frames per second.
Another important issue with LCD display is response time, older displays
responded slow enough that they had problems with fast action video.
