It depends on:
a) which version of the program you're using, and
b) how you plan to display the video on your TV (ie, BluRay disc player, DVD player, Apple TV player, computer hooked up to TV, etc.)
What version of Premiere Elements are you using and on what computer operating system is it running?
In the absence of that information, I will generalize
You set the project preset to match the properties of your source media.
In your case it would appear to be 1440 x 1080 HD Anamorphic 16:9 @ 25 interlaced frames per second. Assuming that to be correct....
If that is the case, then the project preset for you would be PAL AVCHD HD1080i25 (assuming audio is Stereo not 5.1 channel).
When it comes to export, use the export choices with 1920 x 1080 in the description.
Both the 1440 x 1080 HD Anamorphic 16:9 and the 1920 x 1080 give the display of 1920 x 1080. A 16:9 flag stretches the 1440 x 1080
to 1920 x 1080 for display after encoding. The 1920 x 1080 is 1920 x 1080 and does not depend on a 16:9 flag for any video stretching for display after encoding. You make this choice to avoid any 16:9 flag - player issues.
Please review and consider. Any questions or need clarification, please do not hesitate to ask.
