Hi, I recently re-installed XP onto a new HDD and now my videos with MPEG1 (VCD) codec can't play properly. I can see picture and I get audio but the picture is far from smooth. Its jumpy. On the previous install of XP I had no probs playing them with Win Media Player 10 and I'm usisng the same codecs I had before. The codecs I have installed are NIMO 5.0. Build 9, FFDShow, Ogg Vorbis, Windows Media Player 8 & 9 codecs, Indeo5, Voxware Metasound and DivX 5.2.1. I used the configurations as recommended from this thread: http://forums.afterdawn.com/thread_view.cfm/48608 I've tried playing the vids in Win Media Player10, DivX Player, Real Player 10 and Nero's Media Player, but get the same result everytime. Since I can get a picture and audio I assumed I had the codec installed, but according to a program called AVIcodec, which tells you what codecs you have installed, I don't have the MPEG1 (VCD) video codec or the Mpeg-1 audio Layer 2 codec installed. I tried searching the net, using Google of course, looking for the codec to download to see if it would fix the prob, but I couldn't find it anywhere. Does anyone know where I can get it from? Thanks, PCThug.
