Weird Technical problem

[morgandawn]

 I am using an older Panasonic DVD recorder to convert VHS tapes into playable DVDs. Today something odd happened.

I cannot get any sound from the  2 most recent DVDs. The various DVD playing software (MPH-HC, VLC, even the included Windows Media Player) have been updated.  They can all play DVDs created by the same DVD-Recorder yesterday with sound. The software programs can play all other files (even vob files) with sound. so I know they are not muted. And I rebooted several times.

The 2 most recent DVDs will play inxlorp 's laptop with sound (using the same software) and of course can be played on DVD machines with sound.

My first thought was codecs!!!, but I don't even know where to start when it is something that impacts so many different programs. VLC comes bundled with its own codecs, so I tried uninstalling and reinstalling MPH-HC and VLC with no luck.   As a test I downloaded two other free DVD players -  BlazeDVD abd KMPLayer and they too are having problems with just those two DVDs. But all the other machines in the house can play the DVDs.

edited: just to be safe I downloaded k-lite and also ran gspot - it says the proper codecs are installed.

edited: even weirder I checked the sound controls and the "speakers" show there is sound (the sound bar is moving up and down). I also updated the speaker drivers.

That's just bizarre. It does seem as though it's an issue specific to that computer, though, rather than the DVD recorder, because the DVDs play with sound on every other device.

Would it help, do you think, to contact an AV tech wiz, like Ian?

I might give that a try. One other item to note is that the alternative player MPC-HC started freezing last week when i started playing DVDs or VOB files.

Okay. I had this problem last year. It was super weird. It ended up being an audio setting for the DVD player in my computer. I had to check something like "Yes, I would like the DVD player to use the computer's speakers!" I kid you not. I think I got to it by checking the properties of either the computer's soundcard/speakers or the properties of the DVD player installed in the computer.

Drafts. I went looking and everything seems to be checked. It only happens on these 2 DVDs so I am still leaning towards a codec/DVD recorder issue.

Interestingly weeks beforehand MPC-HC (or whatever it is called) stopped working. VLC has had problems for the past year since they did an upgrade - it stutters when playing vob files. Have tried many recommended fixes.....
