    Synch problem

    I noticed some BIG problems with my audio/video synch:

    when i play the avi i just ripped, in some scenes it seems going perfectly synched, but in others, it lost the synch of a second ...
    i use nandub to synch them ...
    any suggestion?

      A few possibilities:
      1. The video is resolution is too high for your processor to comfortably decode.
      2. The audio speed is not the same with that of the video (ie. different framerates), resulting audio synch.

      Does the synch problem occur gradually as you go along the file, or is it always there whenever you jump to the specific point on the video?

          i dunno ...
          my cpu is a tb700 with 256mb of ram, running on xp with a maxtor 80gb@7200rpm

          anyway at the 20th time it worked ...
          but now i noticed another problem ... when i play it with bsplay, randomly it stops for two or three seconds [the audio goes on], and then it restarts to play, jumping the scenes, perfectly synched ...

          it starts to get me mad ;\

              You actually counted it...

              What is the video resolution?

                      That resolution should not be difficult for your processor to handle. To be sure, play the movie again (With no other memory nor CPU-intensive programs running) and in the middle of playback, press Ctrl-Alt-Del and go to Task Manager -> Performance. Under the CPU Usage level meter, is it at a constant 100%? If so, it is a sign that your CPU is having trouble playing it.

                      Also check that DMA is enabled for your HD and that it is not sharing the IDE channel it is on with any slow IDE device, like a CD-/DVD-ROM (UDMA-2 and lower, or PIO). Or perhaps, it was just a sign that the HD is dying?
