Yes they are HD it normally says in the title or NFO if its a 1080p or 720p

If its 30 or more GB in size then its an exact copy if its much smaller then its been encoded to x264

Quality will depend on who ripped it and what it was originally encoded in MPEG-2 or MPEG-4 and whether it was
single or dual layer

I guess your be asking how to play it next :)

going to play it with cyberlink dvd,says 720 in the nfo and its around 8gb in size just was unshure that it was still hd as i have just wasted 14hrs down loading the true blu-ray one because it had so many bad files :(

If its a mkv then cyberlink wont be able to play it you need to install a H.264 codec and a filter/splitter and a media player
that allows you to select which codecs to use for different files

Cyberlink will have installed its own H2.64 so you don't need to install one but some are better than others, I personaly use
ffdshow for H2.64 along with Haali Media Splitter which you will probably have to install

If you install "The Core Media Player" it will install Haali Media Splitter for you and will probably play it using cyberlinks codec

I use "The Core Media Player" or "Zoom Player"

Funny thing about x264 files (mkv). I have dl a few and recently downloaded You Only Live Twice. Starts off playing fine from PC to LCD TV and then the sound goes out of sync, in dolby digital 5.1. Same with others I have tried including The Sting. I put this down to my PC being to old and slow (pentium 4 2.4ghz, Nvidia gforce 6600GT graphics) I have a sound card that is dd5.1 compatible. Then I thought I would try and convert to a vob for playing on the ps3 and the same thing happens here when played back. The Sting struggles to play any sound from the vob version (its intermittent on and off) in the ps3 in dolby digital 5.1 although it does handle it in normal dolby stereo. Anyone else have problems playing these files back?

As far as I know, HDTV recordings come in x264 format simply because dual/quad core cpu's are not efficient ( the way the data is an-alysed ) in using the Xvid codec between cores, whereas the x264 can happily work with multi-core cpus and effectively lowering encoding times on PC's equipped with these.

HDTV is mainly broadcast in H.264/AVC, X.264 is a free encoder designed to encode H.264/AVC

If you wanted to get the same quality as H.264/X.264 using Xvid or Divx you would have to use much higher bitrates which would mean much larger files

So I am right in assuming then that its my PC being single core 2.4ghz thats the reason that there not encoding properly and not playing back properly. I need to upgrade my PC. The next PC I get is gonna either be dual core 3.0ghz or quad core 3.0ghz, depends if the prices drop for the quad core and when I finally get around to it.:D

im running intel q6600 over clocked from 2.4ghz to 3.4ghz,no more amd for me they over clock crap

I re-encode to avchd and play them on the ps3. Looks great!

i have a media tank that supports full hd has hdmi and ethernet to upload mkv etc to int hard drive. i can also stream from pc but with it being wireless hd stuff is a bit stop and start but from hard drive its perfect.only thing is you dont want to watch sd stuff anymore.

Cant you run and setup CoreAVC properly?

CoreAVC™ for Windows @ 720p video at 24-30 frames per second

2.2 GHz Pentium 4 or faster processor
At least 512MB of RAM
128MB or greater video card
Windows 98, 2000 or XP

CoreAVC™ for Windows @ 1080p video at 24-30 frames per second

2.8 GHz Pentium 4 or faster processor
At least 1GB of RAM
256MB or greater video card
Windows 98, 2000 or XP

VLC media player is good :king-041:

Yes M8 I know but try playing 1080p MPEG-4/H264 with it :smilielol5:

You need to use a player that allows you to select which filters are used for each codec type which is
where most peeps go wrong they install the codecs but don't configure the player to use them :ack2:

CoreAVC is probably one of the most cpu friendly

Hence you only need a 2.8 GHz Pentium 4 to run 1080p when using CoreAVC :D

LOL, i don't bother with 1080p coz me eyes are goin :smilielol5:
can't see any difference so the smaller files @ 720p does me :respect-055:

Thanks for the coreavc info. Been having trouble with sound sync problems on x264 mkv files and I now know it was caused by a component in the community codec pack. This was also causing problems when trying to convert mkv files to vob the resulting files were also playing out of sync on my ps3. But now after uninstalling the community codec pack and installing coreavc they are converting perfectly and playing perfectly. So far anyway.:applause-003:

so just to clarify, as i am terrible reading between the lines lol, if i download a film that is is x264 mkv and the nfo says it has been ripped from a blu ray, this file will be Hi-Def.

I have seen a few of these around and was thinking of grabbng a few once i set up up my media pc under the plasma. Be easier than getting 30gb blue ray image.

Yes but a lower bitrate hence the smaller size, but on the whole the quality is excellent depending on the source and the ripper

DivX have started beta testing on their own H2.64 decoder which supports multithreading across 8 CPUs its meant to be faster than CoreAVC :king-042:

ok so for a definitive answere, which are better quality, the mkv or a dvd?

i am about to grab one and dont wanna waste the bandwith.

thanks chaps

One is hi def and one isn't so which do you think ?

If the original blu ray or hd dvd was a good transfer and its been ripped by someone who knows what
they are doing then it can be fantastic quality

My advice is download the first two RARS that will be either

movie.rar
movie..r00

or

movie..r00
movie..r01

Then use winrar to extract the movie from those two RARs but you have to make sure in winrar you
check the box "Keep broken files" that will give you a sample without downloading the whole movie

BUT you must have the correct first Rar !

ok tnt will do that. if i was to encode them to dvd though, to play them on the ps3, i would assume that would lose quality right,
