Just wondering if anyone can point me at what to look at.

first of all I have mpg clips from other past editors (call it birthday clip). I can play these clips with Window Media Player and have sound. Currently with PD5 I have sound upon capture to mpg (mpeg 2 format). When I try to play the mpg clips or the completed mpg produced file all sound is lost. If I go back into the editor and again edit the project, all sound is heard while in the editor. What is it about capturing Mpeg 2 clips with PD5 that creates mpg clips or projects with incompatible audio tracks for windows media player?

Again media player does plays sound on other older mpg clips created outside of Power Director.

Last unknown to me is exactly what the difference of mpeg 1 and mpeg 2 is. I think both have the same extention of .mpg? I am not positive if my birthday mpeg is mpeg 1 or mpeg 2 format. Birthday has the .mpg extention. I'm assuming media player is without fault because this old Birthday mpeg plays sound. I hope there is not some quirky difference between mpeg 1 and mpeg 2. thus corruption in mpeg 2 play back and not mpeg 2 playback of sound....I'm reaching trying to think of what I haven't yet learned about all this.

I appreciate anyones input as I'm looking at just a reinstall to see if I can fix this from a clean system. By the way the editor is not on the net, really does not have much in the way of packages installed on it. Its pretty much XP, itunes, Office, directx, adobe acrobat, PD5 and an install of AOL 9.0 which hasn't been even been used. I'm not sure if AOL is the devil. Deleting AOL, PD5 and reinstalling PD5 didn't do anything for creating mpeg 2 files with sound.

Use a search engine to look up mpeg 1 and VCD (Video Compact Disc)
Frame Size: 352x240 (NTSC) or 352x288 (PAL);
29.97 frames/second (NTSC) or 25 frames/second (PAL)

Mpeg 2 = DVD IF the correct frame size and compression rate is selected during the render process. The range of which is variable and the output quality reflects this.

Both mpeg formats use the mpg file extension. You can also compress files outside the fixed (lower) VCD range and these will also carry the mpg extension but wont be playable on your TV connected disc player. VCD was the format used extensively prior to DVD becomeing cheap etc etc. VCD also was more widely used in China than the rest of the world.
There is also SVCD....

WMP - perhaps you have a codec issue preventing mpeg being played/read correctly. WMP is not my preferred Mpeg 2 player software.

thanks, so now I have more of an appreciation that not all mpg's are created equal by a single standard.

I poked around and I got a suggestion that if WMP 9.0 does not play sound for only some mpg's that I likely have a codec problem. They suggested to get an updated one. But what to look for in a codec Mpeg2 if you don't know exactly what is causing the problem with the sound playback.

On the codec topic I can't play back dvd's on my pc as I have not yet bought one for dvd and installed it. I'm looking for this codec and then a codec update to play mpeg.

2 things come to mind.

1) are there separate codec's for these two applications. (I'm thinking so) Can you get codecs for free or should I just buy one from cyberlink. I see a wide cost difference for codec software. I'm not sure what I should buy or look into. I checked into one codec for dvd and it seemed to be part of a sweet of codecs. Is that what I should be looking for a group of codecs for about $50 and cover dvd and mpg.

2) You stated that windows media player was not your favorite to play mpeg 2's. What's a good alternative that hopefully does not cost much.

Hi wayne,

I've found that WMP is apt to shudder/jerk terribly when playing an mpeg2 file.

PowerDVD Standard or PowerDVD Deluxe (is the one i use).

I assume both of these products include their own codecs for dvd and maybe mpg 1 and 2....others?

I was looking to buy a cheap $10 windvd codec from an unknown unproven site after this mpeg2 play back issue was resolved. Some sources were looking for upwards of $50 for windvd codecs. So to the cause of dvd playback I'm committed to buying something anyway.

Would then your suggested cyberlink pkgs more or less likely buy me out of both my Mpeg 2 play back problem as well as obviously playing dvds video on my computer. Operative word being "Likely", I don't beat up people for giving me their best guess on the mpeg 2 issue.

Could I email you a couple seconds of Mpeg2 to determine if the video I have from PD5 is flawed somehow in its creation.

I'm still wrestling with why some mpeg 2's created on my old computer play sound but those created on this new clean XP machine created by PD5 do not play sound. If my old Mpeg 2 files didn't play sound through WMP I would be ready to buy into your thought that the 2 year old MPEG clips could have been created in a not so friendly tweeked twist on MPEG2. But the fact that I have the opposite situation and it is my PD5 that creates the files not playable seems to be a problem that should easily be documented for WMP 9 in XP Pro. I'm thinking ahead wondering what WMP and the Cyberlink player might have in common that could continue to cause me failure to play back sound.

Soo....
1. do you think the suggested cyberlink purchase stands a good chance to fixing both dvd and Mpeg 2 playback.

2. do you think I should check anything else or proceed with #1 and cross bridges after that?

Wayne, send me an email either PM your own email address or see the signature image below.

CyberLink do a codec option: CLICK

Will it resolve your problem... I don't know.

Send me the email and perhaps resolve the dilemma on the files themselves..
