Since you do not tell how you transfered your movies one can only guess
the correct way to move movies and photos to a new system is Connect the two Macs together (network, firewire target mode, etc) and drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac and it will open the library and convert it as needed and you will be ready move forward.
My guess is that you exported the contents of the library - there are several problems with this is I guessed correctly - you get the previews of all images which for a movie is a JPEG of the first frame, you lose all of your organization (albums and folders and any event reorganization you have done) and depending on the options you check you may lose palces, keywords and other metadata
It is possible that disk recovery software like File Salvage can find some or all of the movies - the free download will tell yu what can be recovered - you have to purchase to actually recover
Sorry, I didn't mention that the entire contents of the older MacBook was transferred to the new MacBook using Migration Assistant at the Apple Store via Ethernet. Everything else - Music, Documents, etc. transferred as expected, with no glitches. Opening the new MacBook looked EXACTLY like my old MacBook (just on a smaller screen).
The movies worked fine on the 17-inch and whatever version (I don't remember that info) of iPhoto was on it.
Thanks for the advice about File Salvage. Running the free version on the G-Drive might be worth a try. Have you used it successfully for similar situations? How does it know, and let me know, if the files it's trying to recover are movie files?
Thanks for the reply. I think you're right about problems on the transfer end. I sure wish now that they hadn't suggested erasing and re-using the TM drive, but you live, you learn.
By the way, stalking these discussions I see you're a major contributor. I took many of your suggestions before I resorted to this. Thanks for all your time and contributions.
I have not used file salvage but it gets good reports form people who have - and it costs nothing to see what it will do
migration assistant unfortuantly has a really bad record with iPhoto libraries and my recomendation is not to use it for the iPhoto library - but that ship has sailed - I do not remember reports of it losing the original of a movie though
