Ok so ive outputted my laptop display to a 47" TV @ 1920*1080. BUT when playing some (not all) 1080p movies it either out of sync with video or stutters.


Seems if i play them with on the onboard display 1280*800, its fine.

Laptop runs ATI Mobility HD 3450 256 DDR 500Mhz CPU & 500Mhz Mem (is that 1Ghz then?). Ive tried VLC, BS Player & KM|Player with AVC Codec.

Reinstalled Vista 32-bit onto 3GB RAM, 2.10 Dual Core AMD Turian CPU, no change.

Anything up to £100 i can buy that will sort all my problems out?
 
That should be more than enough to do 1080p.

Something's going wrong.

Have you verified that the movies (which I assume you've downloaded) work stutter free on more capable hardware?
 
Try monitoring cpu usage during playback (in particular on a per-core rather than overall basis). Could be that cpu isn't up to the job.

Try the CoreAvc codec, its not free, but it will reduce the CPU load by a reasonable amount ( if thats the problem ) when playing x264

I download a lot of 720p US TV shows - usually in mkv format.. I use coreavc codec and VLC player. I'm finding almost everything I watch has sync issues, minor usually, between 50-100ms, and I can tweak it in VLC, but it's still annoying because I'm sure they're encoded correctly, so I'd love to be able to fix it and just have working videos straight away.

Anyone in a similar boat? I'm going to try the klite codec pack to see if that improves things.

I do use HDMI -> TV and Optical audio -> Amp, but I can't believe that would add a/v issues.
 
dodgy downloads? :D

if you've got VLC try offsetting audio +/- to get it in sync

EDIT: get k-lite codecs, all the codecs you'll ever need :)
 
Sorry, I think I misread your post.

If this is for streaming video (as you say in you title) for things like Youtube/Iplayer in HD, then your laptop is simply not powerful enough to play them. AFAIK, pretty much all streamed video is very CPU intensive, so a 2.1Ghz turion is gonna have a hard time keeping up.

If I have got this wrong and you are referring to video files (eg h.264 .mkv) then please refer to my first post or try one of the other good suggestions.
 
I think from the players he mentioned he's not talking about web streaming Youtube etc, also no web streaming does 1080p
 
i had this problem on my desktop with a dual core cpu @ 3.8ghz. 720p movies would work fine(not all of them though) but 1080p would not, almost always stutter'd or was not sync. also if it worked ok for a bit and i would skip a bit of the movie then it would go back to not being sync and stutter.

i resolved this by changing to a quad core. never had a single problem since i've changed the cpu to quad and its at stock 2.66ghz. I read about ATI and powerdvd or something that allowed the gpu to do some of the work instead of the cpu but powerdvd does not support mkv formats.
 
I use MPC-HC on Windows 7 x64 using the Shark codec pack configured for hardware acceleration using my 5850. I got stuttering problems on 1080p video streaming from my server using 200AV powerline connectors, have now hardwired connection with cat5e to resolve.
 
I don't think your CPU is up to the job, play the Video(s) and post your CPU usage. I think you'll be maxed out...from what I've seen you need a Duel Core at ~2.4 for 1080p playback (especially for large .mkv's)
