Welcome to the forum.
What platform are you on, Mac, or PC?
What are the full specs. of those files? See this ARTICLE for how to gather those specs., including the CODEC used.
It is likely that your old computer had the necessary COCDE's, but they are not installed on the new one.
For a bit more info on CODEC's, see this ARTICLE.
I'm with Bill on this. What model of camcorder is your video coming from and what format and resolution is it?
And, when you started your Premiere Elements project, which project settings did you select?
I'll have to take a look at the project settings, but the sung I was trying to install with my pictures was purchased off itunes.
Now I have another problem with my DVD's I bought and All-In-One Hp computer. It is one of the best. I love it. Here is My problem with burning a dvd. I go though the process on Adobe Premier Elements and everything seems to go fine. The burned DVD plays fine on the computer, but doesn't play on my home DVD player. The home DVD player is a current model from Toshiba and the latest technology. When I put the DVD in the Toshiba player it just keeps trying to load with no success. I did not record in Blue Ray, just used standard format. I tried it several times with the same results. Any ideas?
Create an ISO (Encore) or folder on your hard drive (Encore or Premiere Elements) and then use the FREE http://www.imgburn.com/index.php?act=download to write files or folders or ISO to disc for DVD or BluRay (send the author a PayPal donation if you like his program)
Imgburn will read the ACTUAL disc brand from the disc, which is not always the same as the box label (Memorex is notorious for buying "anything" and putting it inside a Memorex box)
When you write to disc with Imgburn, use the slowest possible speed setting, so your burner has the best chance to create "good, well formed" laser burn holes... since no DVD player is required to read a burned disc, having a "good" one from a high quality blank will help
Use Taiyo Yuden single layer or Verbatim Two layer
Or Falcon Pro for inkjet printable Two layer
Wait a minute! Did we solve the first issue or not?
I don't understand why you're starting a brand new topic mid-thread. It makes it very difficult for us to track what's going on as far as your original problem is concerned.
Thanks I'll give it a try.
