No sound when playing dvd's I've played successfully before.
I have never had trouble playing dvd's until yesterday. No sound when playing now, but sound works on everything else. I have a Dell notebook Windows Vista. I have defragmented and cleaned discs. Help!

Try booting to safe mode and try playing your DVD there. If it doesn't work, then try updating the driver of your DVD player by going to the device manager. If no go, then try resetting the DVD player by removing it and putting it back in.
If it doesn't work, then you might need to buy a new one.
By the way, do you have RadarSync in your computer already? RadarSync automates your computer's driver updates. If you don't have it yet, then I suggest that you install it so that you can avoid from having outdated drivers and device drivers related problems.
If the audio works good otherwise (you can play some Windows sounds or go on Youtube and play a clip), then you likely have a partially bad DVD drive. I've seen partially bad DVD drives that had done exactly that. Don't know what model HP you have, but HP usually puts out its service manuals on its website and getting a DVD dive replaced yourself shouldn't be overly difficult. Best place to buy a replacement drive would be on eBay, and anything other than a DVD-write should be pretty cheap ($10-$20); DVD-writers cost slightly more.
To play DVDs you need a couple of things, a drive capable of reading your DVDs, a program to play them with and the correct Codec (compression/decompression) software to tell the program how to *read* the DVD. The ?no decoder found? error would tend to indicate you don?t have a program capable of playing DVDs installed or its not installed correctly.
What program are you trying to play DVDs with? The free versions of Real Player and the newer versions of Media Player will work for the most part (I?ve had more success with Real) but they sometimes have problems decompressing the DVD in order to play it. In that case they typically will try to go to their respective web sites to update themselves and hopefully get the software they need. My experience with these programs is that if they are up to date and have the latest Codec?s they can generally play most N. American commercial DVDs, however, I have been let down at the wrong times by Media Player and occasionally by Real as well
Current version of free Real Player (make sure your PC meets the requirements first): http://www.real.com/realcom/R?href=http%3A%2F%2Fforms.real.com%2Freal%2Frealone%2Frealone.html%3Ftype%3Drp10_dlp_1%26bb%3Dtrue%26pcode%3Drn%26opage%3Dreal_superpass%26src%3Drealhome_bb_0_3_1_0_0_1_0%2Creal_superpass%26pageregion%3Dright_bottom_text&pageid=unagi.8083642&pageregion=right_bottom_text&src=realhome_bb_0_3_1_0_0_1_0%2Creal_superpass&pcode=rn&opage=real_superpass
Generally I prefer to rely on InterVideo?s WinDVD, for about $40 it?s been a great investment for me:
