Is it possible to achieve 24fps with PAL Version if so tell me how?

CineForm's application does a great job of working with Cineframe 24 if you go that route.
Changing 25p to 24p is exceptionally easy, simply reduce speed by 4%. Any NLE can do this. Sony Vegas does a very nice conversion to 24p from 25p or 50i.

I like to work off of the original .m2t on the editing timeline, so that I only have one render, not multiple generations. So I work with the 25fps .m2t file.

When editing 25p or CineFrame25 footage in Vegas, on a 25p timeline, simply change the counter from seconds and minutes to absolute frames. Then, after you've finished your edit and are ready to render, go to the end of the last clip. Hit Ctrl+G, which selects the timeline position number (frame number), copy the frame number, then change the project settings from 25p to 24p (or 23.976p for DVD and Broadcast). You'll notice the frame number at the end has changed (gone down). Now, press Ctrl+G again, and paste the frame number, then hit enter. The cursor has now jumped to that frame number. Hit "M" to lay down a marker on the timeline, so you know where everything needs to end. Then, hit Ctrl+A to select all events, hit "G" to group them, and then hold the Ctrl key as you click with the mouse on the last clip and drag it to the marker. Make sure all your audio tracks that you stretched are locked to the pitch, so that Vegas' less than efficient resampler doesn't botch up the audio (I use the freeware sound editor Audacity to speed the pitch back up 4% without changing the length).

Note: this method requires that you don't lay down music until after the stretch, unless you want your soundtrack to sound a little weird.

The upside of editing 25p (or CineFrame25)? No pull-down artifacts. :)
