Comment (by Francesco Bucciantini):

 I live in PAL land, so I always had to deal with either 25i SD and FULL
 HD, so I don't know for sure about 29,970i. I'm just glad that as far as
 DolbyE is concerned for PAL 25i, we have 1792x25=44800Hz

 The same is true for 50p in UHD for PAL, by the way, 'cause it's still
 44800Hz, in fact it's still being made as if it was a 25fps stream, but
 with an higher line positioning.

 I also gotta say that the hardware I have over here is pretty old and can
 only play a maximum of 48'000Hz, but given that as I said we're a European
 broadcaster it wouldn't make any difference anyway 'cause no matter if
 it's a 25i or 50p stream, it will always be 44800Hz upsampled to 48'000Hz
 upon playback. ;)
