No Audio on DVD
I have a dvd of a lecture. When I play it, the boilerplate music created by
the software used (I don't know what it was) plays just fine. I then click on "Play" and then on an image of the lecturer. The video is just fine, but there is no audio. I am running XP and have tried several different video players. I tried the dvd on my laptop with Vista, and it works fine. I even tried it on my TV's DVD player and it works fine. But not on my XP desktop. Since I can hear the intro music (which is not part of the recorded lecture) I assume it has nothing to do with my speakers, mute button, etc. This is very strange. Anyone know why? |

Almost certainly your PC doesn't have the required codec to play the audio from the DVD. You neglected to state what application you are trying to play the DVD with, but if it is Windows Media Player, then problems like this are not uncommon as WMP doesn't come with any of the codecs required to play DVD video discs as standard. |

No Audio on DVD
I've tried Windows Media Player, WinDVD, Quicktime, and now (at John Inzer's
suggestion) VLC Media Player, all with the same result (sound with the intro that comes with the software, but no sound with the lecture). I've played lots of other DVDs without a problem. Perhaps I don't have the required codec, but I'm not sure what that means or how I got about getting it. Thanks, Bob "M.I.5¾" wrote in message ... "Bob" wrote in message ...

No Audio on DVD
"Bob" wrote in message ... Tried that; still no sound. Very strange since it's OK on my laptop and a friend who used the same DVD on her PC had no problems. After downloading the codec pack, I tried it on Windows Media, Intervideo WinDVD player, and VLC. No luck. But thanks for trying. You also don't say where you are on the planet, but in Europe one of the permissible codecs for audio on a DVD is MPEG. No commercially produced DVD actually uses it because of issues with it. Is it possible that your DVD has been mastered with this particular codec and this is why it is the only DVD that doesn't play sound on your PC. If you are in the US, MPEG is not a valid codec and US specific DVD video players won't recognise it. I am advised that some DVD players and some PC based DVD playing utilities won't recognise MPEG sound on any NTSC format DVD. However, I note that you can get it to play on other platforms so I believe this is still down to a missing codec. Maybe this might help with finding out what codecs you have http://www.updatexp.com/sherlock-codec-detective.html Or try this codec manager http://www.nirsoft.net/utils/mmview.html |

tell you which codecs are used, and you can then check whether you have it. "Bob" wrote in message ... I'm in San Francisco.

No Audio on DVD
I tried GSpot; it brings up all the files in the Video_TS folder of the DVD.
For the several VOB type files, GSpot says the Codec should be MPEG2 and that the status is "Installed". For the BUP and IFO type files, GSpot doesn't do anything, but perhaps these files don't need a Codec. I assume that if the status is installed, it means I have it.

No Audio on DVD
That is certainly one (uncompressed) audio codec used in DVDs, though not
too often (AC3 is more common now, as it uses compression). Personally I don't have any DVDs that were encoded to DVD_LPCM_AUDIO so I can't test whether they play sound here (WMP 11 on XP pro SP3) In the stat. box in the Audio section, does it show 'codec installed' highlighted in green? You could also use GSpot to see if it will produce the Audio: With the vob file fully loaded into Gspot (in the video section, wait until it has stopped scanning), at the bottom of the Gspot pane (proposed codec solutions and tests), click on 1 in the MS/A/V column, then click on 2. Check whether you hear sound when you play the file in the little popup box. If GSpot can play the Audio, WMP should generally also be able to do so. Third diagnosis, in Gspot, system menu, click 'List media types' (which lists the media types found in your registry). In the window that opens scroll through looking for DVD_LPCM_AUDIO in the Designation column (left most column). There may be several entries (I have 4, corresponding to different media types). Right click on them in turn, click 'list all filters accepting this format' to see whether you have any appropriate filter installed (highlighted in blue) for each. On my system AC3 filter is shown as a match for 3 of the 4 media types, but you already tried that and it didn't work. The fourth media type (MPEG2_PACK) shows ffdshow to be a match, but not AC3. So maybe that is the media type (audio) of your vob file. If you haven't tried ffdshow, you can download it from http://www.free-codecs.com/FFDShow_download.htm (the topmost link or either of the two mirror sites listed). When installed, click start. programs, ffdshow and open the audio decoder configuration. Check that LPCM is enabled. If not click on its decoder entry and select enabled. If all else fails you could convert the audio stream to, say, AC3, using, for example (free) Super coverter. Its main page is http://www.erightsoft.com/SUPER.html Unfortunately you have to go through three pages of bumf and user instructions before you get to the place for the download; persevere :-). BTW if not already done, I would uninstall the K- Lite codec pack. That's about the limit of my knowledge I'm afraid, so if none of the above helps I can't think of anything else you could try.

Well I got it to work, but not quite sure why! If I play the DVD with VLC
