What is "135 Kbps MPEG-1/2 L3 2ch"?

[smackyourfupa]

Not sure if this is the right forum so please move if necessary. I dowloaded a season of Cheers and the files seem to be PAL so I started reencoding them using Auto GK (which I use all the time) so that I can burn them on a DVDR as data files and play them on my Philips DVP 642 DVD player. The audio is coming up as 135 Kbps MPEG-1/2 L3 2ch on Auto GK and I've never seen this type of audio before. Does anyone know what it is? Also, the video resolution on most of these files are512*384 but some are 528*400 ,all 23.976 fps.

well I just read on here that DIVX/XVID files cannot be PAL. I assumed they could be because alot of video files (avi files) I download dont play correctly on my DVP 642 so I have to reencode using AutoGK. The audio is fine but the video is blocky and distorted. Anyone know why? Resolution?

MPEG-1 Layer 3 (MPEG-1/2 L3) is the "proper" name for what everyone calls MP3

2 channel (2ch) means it's a stereo track

the bitrate (135 Kbps) is what the audio has been compressed down to (uncompressed CD audio tracks are about 1.45 Mbps) ... as 135 is a rather "weird" value, it's probably encoded using a variable bitrate (say 128 Kbps mostly, and some 160 Kbps sections which "average out" to 135 Kbps)

Most of my divx files read 128 kbps CBR MP3 2ch. What's the difference between those and the ones that read 135 Kbps MPEG-1/2 L3 2ch. I know the bitrate is variable, but whats mpeg 1/2 L3?

MPEG 1/2 L3 = MP3

[smackyourfupa]

there has to be a difference as to why most just say mp3 and some say mpeg 1/2L3

Try using Gspot and see if it reports anything different.

BTW, you can play PAL video on the DVP-642 so you don't need to convert just because of that.

yes PAL DVDs...not PAL avi files. Like i said though, I read PAL/NTSC does not apply with DIVX files.
I do need to convert some of these files though. Whether it is because they are PAL or not, like i said, the video is all screwed up with some of them. It is pixelated and blocky and unwatchable. However , if I run the file through Auto GK it's ok. Heres what I'm talking about...

That's a custom matrix problem. Press the System/Menu button on the remote twice when the picture is messed up. That usually fixes it.
