Streaming Video to TV Stutters?!?!

[whatthefrenchtoast?]

I just built a brand new machine a couple weeks ago. Specs are good, and this was built with video editing and gaming in mind. I have Abit IPpro35 motherboard, 2 GB RAM, XFX Geforce 8800GT Vid card with dual DVI and Svideo out, Vista Ultimate. Tons of cooling in Antec p182 case. I have setup widescreen 19" HP monitor through DVI and run Svideo to component cables to my Mitsubishi 65809 widescreen HD(only 1080i, but still HD). I want to stream HD and regular video straight to the TV, and have been. HD looks great, and video quality is surprisingly good. One issue, I have noticed, is that when streaming to the TV, the video, no matter what the source, will stutter for a second. Not real, real bad, but noticeable. I have played a DVD and streamed standard def video and HD video...all the same. It is not at regular intervals either. I have updated all drivers on machine and done all windows updates. I have loaded codec packs. I have changed all settings and played with all resolutions and refresh rates and still the same. This does not appear to happen on the HP monitor at all. Very sharp and fluid. Is it that it does happen but I just don't notice it because of size? On the TV, I have kept an eye on the resource monitor to see if anything spikes when this happens, but I have not noticed any pattern. I have also tried to disable antivirus, NIC and any programs from running while watching, but still the same. I am a technical person, but at this point, my research and troubleshooting is at an end with no answer. I have also checked event logs but found nothing glaring. Any help anyone could give would be great. Also, just so people know, I am running these movies through the Vista windows media player. Thanks in advance for any help.

AFAIK you cant be feeding your HD screen with HD thru svideo ? Has to be HDMI or component?? Svideo is low quality anyway, even for SD.
codec packs. brrr shiver, detritus. Media player, Ditto. try other players.
one large hard disk?? defragged?
wireless?

Dense posting. Too dense. Needs paragraphs, full stops.

Have you tried different refresh rates and resolutions?

ANd yes, hdmi or dvi would be better.

OK, so I thought that the TV might be the issue. Maybe it could not handle the output since it was an older projection TV and only did 1080i. Well, it died, and I just purchased a brand new Samsung 63" plasma 1080p, and same issue. I was just hoping this would go away. The only thing left is that I have tried using the component cables with adapter for video card, and VGA monitor connection. I have not tried DVI to HDMI yet. That will be next step. I know now it wasn't the TV, and when it streams to computer monitor (19" HP LCD) it is perfect. Is this a throughput issue? Can the cables not handle this? Or is this a refresh issue on the TV? Is it possible that the TV is just too big and it cannot keep up? Is anyone else streaming video to a very large plasma or projection and have same issue? Thanks for any help.

It could be a refresh rate issue. For 24 fps video try use a refresh that divides with 24fps like 24hz, 48hz, 72hz. I use 1080p 24hz on my computer to my pioneeer plasma to get smoooth playback for 24fps dvd and hd NTSC movies.

What video resolution and refresh rates have you tried?

[whatthefrenchtoast?]

I have tried the 1920x1080 (Full HD), but that is it. I tried a couple others but the TV just wouldn't show a picture and said it was unsupported mode. I guess I will continue to go through the list and see if it make a different. I do know that on my old TV, I tried every single possible resolution and the same on all. Right now I have it plugged into the "PC" plug, but I did have it plugged into component connection oiginally. I am also going to see what happens when I get this DVI to HDMI. Could be these cables I am using are just not handling the data transfer very well.

Well, here is an update for any others in case they have same issue. I got my HDMI cable, which by the way produces a fantastic picture as compared to my old cables. I plugged it in and then made the TV to sole monitor and started watching HD movies and regular def movies.....and guess what......NO STUTTERING!! I was so happy, I finally got it resolved.........well.....

I changed the monitor back to the LCD monitor I have, then configured the TV as second monitor and played a movie - suttering came back. The long and short of it is, that this entire problem (well, maybe not entire, cable might have had an effect too as on my old TV I tried to make TV only monitor and it still stuttered) stems from having 2 monitors run at the same time when trying to stream movies to TV.....this just will not work well. If you make the TV the sole monitor, and turn off other monitors, it works perfectly. Just thought I would post this for others to know in case they had a similar issue. Thanks for all the help guys.

If you tried to "force" your older Tv into a refresh that it couldnt cope with, that may have contributed to its demise. Howver you say that all the time you were using two monitors (one Tv and one monitor) off the one graphics card? When you are running computer monitor AND TV your refresh may be limited by what is the primary display eg LCD monitor. This may be set to run at 75mhz refresh, this also reflected on TV. great that you got it fixed.
