I have had the same problem. I found that it was much simpler then I thought it would be and what was being explained here.
When you go to new under the layer menu in the timeline you will have the option to import. Select import and make sure that *all files is selected. Then in after you choose the file you want to import it will pop up a second selection screen. You probably have see this quite a few times. Choose what ever frame rate you want and what type of format you have for your project. Now this is where it is simple and yet easy to overlook. The four sub menus, Project/Clip/Layer/Custom Brush tabs. Under the project tab make sure you select image in the split scene menu. This is important, Make sure that in all the tabs you uncheck single frame. In the clip tab select stretch to project size and correct aspect. Everything else remains unchecked. Under the layer menu check the same options in the Clip tab. The most important step is to make sure that you deselect the single frame option in ALL the tabs.
I hope this helps
I also do videos every week on Youtube to learn this software from the beginning to the end. You can also request a video and I would be happy to oblige!
TVP exports .mov, .mp4 and .avi files on my Mac. If it plays in the native player of your operating system, it should import as well. If not, I have to convert it first.
