For some reason I can no longer import any new videos to iTunes.
I tried dragging and dropping, "add file to library", "add folder to library", "import" I dried dragging and dropping to playlists, directly to the iPhones list of videos but NOTHING works.
I had 3 clips on my iphone that were in itunes since before.
I tried deleting one from itunes as an experiment, and now I can't get it back in.

So, something fishy is going on.

Is there any way I can upload video files to my iphone using some other program, and in that case, where exactly should I put them?

Or even better, how do I solve this issue that I have with iTunes?

Thanks for any help I can get!

When you drag and drop, did iTunes just "ignore" it? In other words, it doesn't say that it is importing the file? Usually this means the file is either corrupted, or rendered in a format that iTunes couldn't not understand. Can you playback the file on Quicktime? If not, that would indicate the problem. Good luck.

maybe your file is in an unsupported format

I've had some problems with codecs, but I can view the files in MediaPlayerClassic, but for some reason not in iTunes.
Or to be specific...I can view ONE of the files i iTunes, and they are all encoded using the exact same codec in the exact same program.

When I drag and drop it completely ignores it, no activity what so ever.

I guess reinstalling iTunes would be in order?
Is there anything I should watch out for when upgrading or does the latest iTunes version work with all 3rd party iPhone applications?

No, don't bother reinstalling as it is likely an unsupported video format. Try playing it back using Quicktime. If it can't playback, then the problem is the encoding. On the ONE file you said it played back on iTunes, right click and convert it to iPod.

See the thing is all of these used to work, and I can even play the ones already transferred in my iPhone.
They are converted to iPod format so the files are using the correct codec.
Now for some reason some of them won't play in iTunes, and iTunes refuses to copy them to my phone, even tho I know they are the correct codec since the exact same files have played on the phone and in iTunes before.

I tried reinstalling iTunes and Quicktime but that made absolutely no difference.

This is just really frustrating and just some direction as to where I could manually put the files on my iPhone would be wonderful.
I don't expect anyone to magically know what's f*cking up iTunes for me, but if someone on this forum has some sort of check on the iPhones folder structure, that would be just fantastic.

Thank You!

Seriously?

Somebody must have an idea of how I can find out where to put the files manually?

. Apple's AVC encoder is slow and quality is nothing special. Its MPEG-4 is not really better. Suppose that at least their AAC encoder is good though. iTunes only support MP4, H264 video, WMV. You can try the DVD to iTunes and Video to iTune videos to itunes
