    Audio delay problems

    Hi all, I'm kinda new to this so be a bit patient with me

    This is my problem, I'm experiencing audio delay between audio and picture. I'm paying movies right off my PC (dvi->HDMI) so I'm using my TV screen as a "monitor" The thing is that the sound is out of sync with the movies not much mu enough to screw with my head lol, anybody got any advice before i turn mad

    Is there a program I can use to fix this problem?

    best regards from Norway

    PS:I have a little suspicion that it might be the cable thats causing the problem but I'm not sure (5M long) And the program I'm using is VLC media player.

    what's your video card? computer specs?

        use mediainfo

        MediaInfo is a convenient unified display of the most relevant technical and tag data for video and audio files


        to investigate further

        sounds like your computer(cpu) is having problems with higher bitrate avi

            If I am on the right track here you should see the sync problems on your monitor also?

            It will be worse when your computer has been running for a while and you are multitasking

            I had some similar issues and thought it was the file, but after a reboot and testing with other software players the sync problem disappeared

            First of all, the FFDSHOW consumes way less CPU power than original DivX codecs, even with maximum post-processing. At the same time the post-processing seems to give excellent quality results and allows more configuring than the original DivX 5 codec. It can even automaticly reduce post-processing if your CPU is getting overloaded.

            too many codecs aggrevate the problem

              True i also have a delay on the monitor, but after i installed the new codec its much smaller. Haven't rebooted the PC for awhile some I'm gonna do that as well. Might there be a delay because of the cable?, I forgot to mention that the mouse cursor is also lagging like crazy on the plasma TV. Could that be the refresh rate on the TV?

                the digital signal travels at the speed of light, I could see a small problem with a circuit
                handling the sound stream

                the long cable might affect the quality of the signal but not the sync

                the mouse cursor is probably your best clue that your computer is being pushed too hard

                if you are running windows xp try the power user tweaks

                    do a three finger salute and compare my screen playing a similar avi to yours

                    my cpu(amd64) is only at 22%

                    my available ram is still 257 megs

                    my video card is slightly lamer than yours

                      Three finger salute - Check! lol
                      well my CPU is at aprox 15% but I'm using twice as much ram as you are I'm at 648 after closing msn and some other small programs. So i guess a little PC maintenance would be in order.

                        look under processes for anything using a lot of ram and cpu%

                        at idle you should have 98-99% System idle process

                            post a screenshot of processes if anything is using much memory? at idle?

                            memory or the cpu might not be the issue
