    Forgive my ignorance, but I just use DVD-RB + CCE to make backups and beyond that I haven't really taken the time to increase my knowledge of video encoding. When I get the error message in DVD-RB, what exactly does it mean when it says, "Possible dropped frames (4)" or whatever number shows up in parnetheses. I have brushed through several forums looking for the answer but everyone just discusses the causes and how to overcome them. I would love to know exactly what it means, how that affects my final output and how many dropped frames is too many. Thanks.

    Thanks. I was hoping someone could tell me what a dropped frame actually is, how it affects output (do audio and video no longer mesh?) and how many dropped frames is too many. When I get them, it is usually just a couple of incidences per rebuild between 1 and 6 frames each time. Does it cause a blip on the screen? What? Everyone seems mildly concerned about it, but what is it that we are concerned about?

    dvd's play @ 29.97 frames per second ntsc and 25 fps pal the loss of a frame or two will not be noticed in playback. you will not see a blip in fact you will not see anything as the frames are not there.

    this may be caused by using an unstable cpu, hot key's, or multi tasking during encode, other than that

    dvd rebuilder will (should) address any issues like audio sync and such as it's nature is to make the files dvd compliant. it will put the audio back into place.

    fi you start getting dropped frames like the guy in the above link let us know how the output is I've never heard of anyone getting 5000+ anything in triple digits I would definately save the source until you are happy w/ the burned result.

    *note; an encoder like hc doesn't stress a system the way that cce or procoder2 does you may try that.
