Jittery HD video from my Aspire 5253 Laptop - Need help

Hello Folks,

I have an Aspire 5253 laptop that works as my Web Server. I rarely use it for anything else. I do, however, want to use it to play videos. It's having problems playing some HD videos that I've ripped from my Bluray movie collection. I've converted some blurays to MKV files. I've tried playing them on this laptop and noticed that the video was jittery. I've installed Shark 007 codecs and VLC media player, but no luck. I can play videos of lesser size, ie M4V with no problem. It doesn't have a bluray drive, so I can't try playing a bluray disc. Any help is appreciated!

Thanks!

Have you confirmed the video you ripped runs on other computers fine? is it a capture setting?

Yes. I"ve tried it on an Argosy Media Player, my primary computer (Windows 7), and an XPS M1210. All of which didn't have any problems. headscratch.gif

in case anyone was still wondering about my problem, I narrowed it down to the file type. Although the MKV video worked on all my other platforms, it just refused to work on my 5253 laptop. I tried encoding the same movie in AVI format. That seemed to do the trick. The videos play perfect in that file format. Still no clue why this laptop doesn't like MKV's, but that's ok since all I have to do is use a different format.

if it was a BDrip to MKV file then it was probably still h.264 or VC1 encoded. That is extremely processor intensive and your 5253 didn't have enough power to decode them properly. Since you converted it to AVI, you probably lost some resolution and also changed the codec as well which allowed your older unit to play the files, although at a loss of quality.

MKV's are just a container format, they can have multiple codecs in them.

You should check out CoreAVC to help playing h.264 files on your 5253, it plays hard and fast with the decoding so it does not maintain 100% quality, but it should work for casual viewing.

Thanks for the response! I tried the CoreAVC codecs like you recommended, but I still get the same result cry.gif. I can tell the computer just doesn't have enough horsepower to keep up. I haven't tried adjusting the settings in the decoder properties, though. Not sure if that will make a difference, any suggestions?

only other option is to upgrade. a not so expensive upgrade is the broadcom crystal HD decoder card. However, you will need an extra mini pci-e slot. otherwise stick with lower resolution video.

That's an interesting solution with the decoder card. I'm not sure if my laptop has an extra PCI-e slot. For now, I'll encode my videos in 720p if I want to playback on this laptop. Otherwise, I'll stick to my 8943g.

Cheers!

Just an update on this situation:

I ended up buying another Acer Budget laptop. It came with a 250gb hard drive. The 5253 came with a 500gb hd. So, I decided to swap them since the laptops were virutally identical. After doing it, both computers worked perfectly. I only had to download a network driver. For the heck of it, I tried playing an MKV on the 5253, just as I stated above. To my surprise, it worked flawlessly. My only theory is the order in which I installed the codecs. So... with that said, all is good! dance2.gif

woot!

I have a acer 5253 with the 1ghz dual-core apu (amd fusion c-50)

 - This laptop is very slow for 32 bits applications.

 - This same laptop is doing great under 64 bits.

 - The video driver from amd that ships with windows is obsolete.

      Download the latest driver from the amd website.

      There is a new feature in that driver for hardware decoding of h264 movies.

 

You have to consider using 64 bit codecs, 64 bit media players. try the k-lite codec pack 64 bit. and maybe or not, media player classic 64 bit...

 

You can also use a 64 bit web browser like Waterfox (customized firefox for 64 bit)

You can try using flash player 11 64 bit, or the beta version still in development that allows multithreading for video decoding.

 

so yeah this computer is good. it has a slow cpu but it can do a lot more than what i expected from it.
