There is quite a big difference in the H.264 profiles used her in NZ  
for 576i/1080i and 720p

The interlaced channels are using an MBAFF/PAFF profile whilst the  
720p non interlaced channels aren't.

This caused major headaches back when ffmpeg couldn't handle the  
interlaced video here in NZ.

Hence I'm not that surprised to see playback differences between the  
interlaced and non-interlaced channels
