On the 1080i60 pull up request, I don't think Astro will entertain that, especially if they somehow figured that the intention is to record off HDMI...
I believe that it is possible that up to 70% of the world population has PAL 50Hz transmission, so the 60Hz (59.94Hz to be exact) community is a minority but they like to think that they rule the world...

Pulling up a 576i (50Hz) transmission to 1080i60 at the decoder is going to cause a noticeable blurriness effect every few frames, same with 1080i50 going to 1080i60.
When I was in the US for work years ago, I knew I was not impressed by British shows on cable there that has been converted from PAL 576i to NTSC 480i (fully SD back then). In fact, the picture looks much better the other way around: NTSC 480i shows converted to PAL 576i as being done by all our local TV stations, Astro included.
Anyway, so is it true that the 1080i50 broadcast is actually derived from 1080p25 feeds, if it is, it helped explain the lack of deinterlacing artifacts, and the resolution is a perfect full HD. This is the way to go...
Hrm... I dont know about you, but I really dislike NTSC 480i shows being converted to 576i.
There are 2 kinds of conversion done.
One is the easy way which is from 29.97fps directly to 25fps... which causes terrible jerkiness in the motion of the video. This is the worst kind of scenario I usually face. Because if you deinterlace the video, no matter its odd field or even field... it will cause jerkiness to the motion. If you use field blending method, it causes ghosting effect, which makes it bad. This kind of conversion is often done to music videos channel. If that music video is really rare and I cant find it elsewhere, I had to stick with it, encoding it in interlaced mode as to keep those lines, let the tv bob deinterlace it... cause only this way the motion stays the best while not causing the ghosting effect.
The other way is kinda long winded, the 29.97fps shows were inverse telecined to 23.97fps and then only fasten by 4% to 25fps. This is commonly done in those US series and you can notice those shows are fully progressive when viewed using a tv card, rtm and other channels in PAL asia countries does the same thing. This method is really good for me, because the main point is keeping those video frame progressive, yeah the audio is off a little faster but i'm still cool with it. For example, Madonna's music video "Celebration" were done this way, so as Paramore's "Decode". Was really surprised to see such thing here because its a very rare case. Usually most music videos were done using the method above.
But have you ever play with a PAL 576i shows converted to NTSC 480i?
Of course this would be bad too but when you deinterlace the video, the motion stays smooth...thats the beauty of it. Choose odd or even field deinterlace, you don't get the jerky crap as of the above situation. Its really funny how this works, but yeah this is what I've noticed playing with it. Not that i support such scenario.
In fact, I'd rather prefer if they broadcast both NTSC and PAL together lol...though it will be annoying to see ure tv gone blank for a while changing to NTSC format when the NTSC video is being broadcasted etc haha.. Keep the original format as it is. Broadcast as it is, instead of convert this n that....really degrades the video quality by doing so. But since HD is the same resolution already, they should maybe get unified and stick with one fps to standardize the whole thing instead of converting here and there.
