I will give that a try Chris. Thanks for the heads up.

I'm going to sound a bit pedantic, but there is no PAL or NTSC any more.  They were analogue transmission standards and they're history.  Once you're in the digital world there's just resolution, frame rate, and either progressive or interlaced.  Even interlacing seems to be on the way out.

I agree with your comment about PAL and NTSC but as far as interlaced video signal goes, I am afraid it will still be on our radar for a while: it is part of the SMPTE 292 digital video transmission standard which requires HD-1080 programs to be interlaced.

If you have a TV that is new enough to play a digital file from a USB stick or other device then it will be able to play any common frame rate and resolution. 

In my experience this is not always true for TVs made for the american market which seems to be less compatible with 50 Hz compatible frame rate. Even 24 frame rate can be problematic on some TVs when played directly from a file. 
For better chance of compatibility I would also suggest an MP4 format.

In any case I would suggest testing… if this is not possible, then having a backup plan to Blu-ray disc, or even a DVD might be your better chance to make it work.
