PAL Video-Stops/Stutters While Playback

[Jellygoose]

I hope one of the experts for PAL and Interlacing can help me with this one.
I haven't dealt at all with Interlacing and PAL yet, as I always thought PAL DVDs are never interlaced. I recently found the Guide by hakko504, and it really helped a lot. However there are still some things that I don't understand.

I see small (barely visible) video-stops in almost all my encodes (MPEG 1 only), (not only on Standalone but also in PowerDVD), and never found a way to get rid of them. However these small stops were only visible after Muxing,(BBMPEG).
Is there any possibility that this problem is due to the speedup from NTSC 24fps to PAL 25fps? Wouldn't it actually be a good idea to add Decimate(25) to each Script to get rid of all extra frames added?
Thanks in advance...

Please make available a small source clip for inspection. Certainly, if it was converted to 25fps by adding a frame, you would want to remove the duplicate.

I'll upload a sample later tonight, no problem. I experienced that these little stops in video are not visible using WinDVD, but are definetely visible when viewed with PowerDVD and also on my Standalone Player. I know there has to be some kind of problem, because they're on the exact same spots whenever I watch them in PowerDVD.

As I already said, this happens after muxing the file either with BBMPEG or TMPGEnc, makes no difference. Thanks for helping!

Edit: Here's The Sample Clip : http://www.angelfire.com/alt/jellygo/STUTTERS.mpg

There's a stop in the video on the end of the sample when the rhino is beaten down, clearly visible if you watch carfully.
Make sure you watch it either with PowerDVD or burnt on CD-RW on your Standalone.

Sorry about that, the sample didn't work! Here's the correct URL. Any help would be apreciated!
