Thank you for replying. I got frustrated and took a break for a while, now I am back. I think part of my problem is the Quicktime movies from my Iphone. I will have to convert them to use them. I don't remember what I need to convert them to in order to use them. The I am using Roxio VideoWave from Easy Media Creator 10.
The movies I made a few years ago play just fine on my AppleTV, I just don't remember how I rendered them.
As for how I moved them into ITunes, I did it the same way I add movies when I buy them. I move them off my desktop by trackpad into the ITunes Movie library.
I can't believe how much I have forgotten! Going between PC and Mac is very confusing. I wish my son had never talked me into the Mac!
You are using too many 3rd party software programs to do what is built into the software you have. (not saying that is the reason, but it is a contributing factor).
Add movies through iTunes itself. File - Add Movie to Library or Add Folder to Library.
Let's try a test file. Grab something, anything short (10 seconds long is all you need).
Throw it into either VideoWave or Copy and Convert Video.
Export it using the H.264 or MP4 option for Compression.
Add it to your iTunes Library as I indicated and see what it does
Archiver: H.264 came out in 2003 But I don't have Creator 2010 installed anywhere to run an actual test it. Likewise any version of Apple TV will play any resolution of MP4 file since Apple TV 2 came out. I run SD on my 2 & 3 all the time when HD is not available as well as some older Laser Disc conversions I have
