if cannot using HDMI and s-video/component output on the same time,
i cant use my dvd recorder d...

i have a new question from ur replied, is it we still can watch HD channel by composite or component output?
mean i have to buy new component cable for my dvd recorder or use back composite cable...

You can't watch HD through composite, period.

i forget my dvd recorder support component input o not,
or all recorder supported?

Agreed. I watched Blu ray using 3plug RCA and SQ and PQ was really good though no Hi Def.
And you can't record HD content coz of the HDCP protocol, hope you know that. Make it simple, watch in HD, record is SD.

Yes the cable needs to be replaced... but Im not sure what cables, perhaps a better type..diff material to avoid interference of other signals since hd involves high data rate.

I have a feeling it will support 2 simultaneous outputs.
Har? are you sure? Why in hell would they use component output then? They might as well just use back composite lol...  If they really do that, they will lose out to those customers who owns old hdtv sets without hdmi input
Im very sure component cable could only go up to 1080i not p.... my lecturer told me that... and when I went to buy the component cable, I've seen so many brands but all of them support at most 1080i....

CompoNENT cables (IE the one with 3 connectors on each end) DOES support 1080p. http://en.wikipedia.org/wiki/Component_cable

I use VCR to record astro show,can i still do that after i change to the new decoder?

i think astro only provide 1080i/720p HD channel,
not 1080p,
right?

so for us that only own HD ready tv,
actually it is enough for us,
am i correct?

How sure are you sports would be in 720p ?  I have a feeling it would be 1080i as well... because 720p requires a lot of bandwidth... and you know astro la...very stingy when it comes to bandwidth... though not to worry my tv will flip if it changes resolution....so i can tell what resolution will that channel be broadcasting =P

Ok, so if progressive video is technically better, why did they allow interlaced video in the DTV spec? Bandwidth is the short answer. Turns out in the current TV channel frequency spacing and using the compression technology that existed at the time of the DTV decision in 1996, there was sufficient bandwidth to allow only HDTV formats that would not exceed the allowed bandwidth per channel. This ended up allowing three formats that pretty well used up the bandwidth. These are 1920×1080p/30fps, 1920×1080i/30fps and 1280×720p/60fps. There are other possible HDTV formats, but these are the three that are at the bandwidth limit. Looking at pixel counts we have roughly the same quantity of pixels transmitted each second for all three with the two 1920×1080p,i/30fps being 62,208,000 pixels per second and 1280×720p/60fps being 55,296,000 pixels per second. Notice the 1080 and 720 formats are within 12.5% of each other, so the bandwidth required is about the same. The 720p/60fps format does have a slight advantage of not having to be quite as compressed as the 1080/30fps formats, so pixelation or blockyness of fast moving objects could be somewhat less. This can be a significant benefit for televised sporting events, although the reason why 1080i broadcasts have more of this blockyness is more due to multi-casting where the bandwidth is divided up to allow one channel to have multiple programs, a DTV feature that was not available on analog TV.

Someone said it differently

modern plasma/lcd can de-interlace 1080i, so we effectively get 1080p, no?

After 12 months, if one decide to not subscribe for HD anymore, then how?
Is it still possible to use the new decorder for normal SD viewing?
The RM20 added to the bill will be charged monthly, starting on April regardless of what package subscribed. In other words, the RM20 is fix?

Thanks
