Hi - I searched but could not find an answer to this. If it is there, please let me know. I have a couple of MPG files which are quite large but when played the player says they are 1 or 2 minutes long. By setting the slider back when the player (WMP10 or DiVx 2.6) is playing I can get part of the MPG to play which would not normally play. Other MPG's files work OK on these two players.

What is the cause and the cure for this??? cool.gif

I assume some part of the MPG file is damaged. It usually happens during transmission (i.e. download or copy of a CD/DVD). I'm not sure how to deal with this as an MPG. You could try writing an AVS and taking it into VirtualDub, and re-encoding (don't even know if you woulg get the whole file anyway), but I assume there is a simpler solution.

Hmmm. One of the files in question was OK and then developed this length/time problem. Could it be associated with an MS WXP update?? crying.gif

IIRC it is impossible to make out the length of an MPG file without parsing it completely first. What WMP does is just guessing a little. It also could be the case that someone has joined two MPG files with copy /b (don't ever do this yourself, it creates broken MPG streams), this could also throw of estimation by a lot. And possibly playback too.

VLC player has a very robust MPG reading. You could even try to remux the files with it, so they perhaps would play fine in other players too.

Bon. I will D/L and try it. Thanks. L8R cool.gif

Stephan - You are right. VLC works. Thanks so much for your help. I could find nothing on the video boards to address this. HA comes through again! tongue.gif

glad it worked smile.gif

did you try to remux them already too?
boojum
OK, remux means . . . ??? cool.gif

Renuxing is the "repackaging" of the video and audio streams in the container... things like improper joins can be resolved this way. It's not so difficult in VLC.

1. open the streaming wizard (file menu) and select your file
2. in step 2 the output method should be file, and encapsulation method MPEG1 or MPEG-PS depending on the type of MPEG stream you have. do not re-encode.
3. press start and VLC will now remux your file.

if everything goes right, WMP should be able to play the file correctly too now.

good luck smile.gif

Hi

Today I experienced the same problem concerning three MPEG-Files that had properly worked before. I tried to remux these with VLC player but that didn't do the trick sad.gif

Does anybody have an idea how to get this fixed?

Thanks in advance for your answers.

Download VCDGear

Make backup copies of your MPG's

open VCDGear and load the first troublesome MPEG, change the extraction/conversion mode to MPEG -> MPEG and click start. repeat for all MPEG's.

hope it heaps
