    Sorry if this seems like a newbie question, but I think I may be over-complicating things for myself. I've downloaded a video online but it came in two avi files. When I try to highlight both in WinAvi Video Converter to make one video it doesn't put it in the correct order. In other words, the second half of the movie seems to start first, then the beginning of the movie second. Am I overlooking something very simple to correct this? My brain's been going in a lot of directions lately, so I'm probably making this harder than it should be. I know you guys are always so helpful on everything else. Thanks from a clueless dude in advance!

    If you have two files (cd1.avi and cd2.avi) on the root directory of your 'c' drive, click 'Start' 'Run' type "cmd" in the box (don't type the quotes)..
    If you are not at the flashing "C:\" prompt, type "cd\" (no quotes).

    Now type (without the quotes) "copy \b cd1.avi + cd2.avi cd12.avi"

    and you will have a new combined file called cd12.avi

    Hey thanks attar - but I'm confused.

    Does that mean that you can just concatenate files together regardless of type or format or resolution or anything and that you'll then get one big file to use with no sync issues???

    Also that confuses me about something - does that REALLY work ok with things like AVIs, WMVs, etc? Don't they have any header information in the files that would get screwed up if you do that???? (I assumed that you could not do a simple concat like that and you needed video processing software to do it that would read the headers & somehow process the files in some way?? That concatenating files like that doesn't really work for stuff other than text files (???).

    And the root of my question is still unanswered - can you mix together AVIs, WMVs, MPGs, etc and not have audio sync issues? I could've sworn I've read some things about that being a problem, but things are a jumble in my head as far as trying to retain & absorb all this ;-\

    Also this reminds me to ask 2 other things - if I use ConvertXDVD v2 to do this and just put all the files together as seperate titles, is there a limit on the # of titles a DVD can have? Because the bunch of files I have now that I want to do this to are very short videos, some only 1 minute in length! So I could have like 80 or 90 title "breaks" - is that even allowed?

    And switching gears - assuming the DOS concatenation works without issues - how would I then put chapter marks for each joined file in my DVD???? That would seem like a long manual task to do right??

    Or, (sorry for all these questions), if I were to use something like DVDFLICK or ConvertXDVD v3 that lets you MERGE all the seperate files together into ONE title - how do you tell those programs to automatically put CHAPTER breaks at all those merge points??? I would think if that were possible it would be a simple switch setting/option of some kind, whereas with the DOS concatenation method since you would be feeding one large file into the program for DVD convervsion it would have no idea where to put the chapters and it would be a manual process that you would then have to go back & do (?).

    Up to this point I've used ConvertXdvd v2 and set the chapters to go like every 5 minutes and never was able to figure out how to put a chapter at a specific point but I didn't really care about that either (how do you do that? and also does it work different in V3?)....I've not gotten into messing with any DVD "authoring" programs but perhaps that is what you need if you do that?? Yes???

    The original post referred to an avi that was split;that they were identical (except for length) is implied and joining introduced no discontinuity as far as the viewer was concerned.

    Joining identical files using this method was to circumvent a particular problem with a particular software.

    Since an AVI and an MKV cannot be identical, then concatenating doesn't work.

    Normally you wouldn't concatenate different titles (except perhaps episodic titles) as the lead out from one movie to the start of another is confusing.
    You would let the authoring program assign each title a menu item then, if required, add chapter marks.
    The addition of chapter marks is by preset interval (but perhaps Nero? allows manual input) and yes it would be tedious.

    I believe that 99 titles are allowed per DVD.

    Right - I am really sorry & apologize to you Attar!!! (And anyone else reading this thread)

    Last night I thought I was reading your reply in a thread of my own (called "Putting mulitiple unrelated videos on one DVD - will there be sync issues?").

    I was tired and had too many windows open, thought you were replying to me, posted in error in this thread before going to sleep (sheesh).
