Those full film frames are broken down into interlaced fields as required with the DVD format. DVD players don't have interlaceing hardware on them. Many DVD players are progressive scan, but only becuase they have the hardware to deinterlace what they get off the DVD before sending it to the display.Guden Oden said:

So 720p upscaling over VGA has been confirmed I think. Alot of people are raving about the DVD quality, any resident videophiles want to do a 'review'?

wow this update is really great, they pretty mnuch nailed every last thing that had bothered me, even little things like remembering where you were in a list after watching/deleting a video, you used to have to scroll down each time.
I do have a couple more additions though:
- for crying out loud, when I press up at the top of a list, bring me to the bottom!
- allow me to order my content by 'date downloaded' I want to see my newest trailers at the top, not scroll through 50 items to play it. I know this isn't an issue with the controller(becaue you can page), but when using the remote it's annoying.
- can we streamline deletion a little? Every tried deleting 40 trailers with the current set-up? it amounts to something like 250 button presses (ok, down, down, ok, up, ok x 40).
Other than that, bang up job, I'm very pleased.
p.s. NucNav you can die a happy man, videos are now stored in both 'game videos' and'videos' in their respective blades

DVD's are encoded natively at 480i. Mainstream TV is still an interlaced signal and that's what the market is geared towards. Newer digital TV's can accept a de-interlaced signal from a "progressive scan" DVD player, but the disc is still encoded at 480i. This is where HD-DVD and Blu-ray come in to play......designed for HD-TV not SD-TV.TheChefO said:

I believe that depending where you are within the dash/program the remote buttons are mapped differently than the controller buttons, I've noticed that when in Media Center if I hit X on the remote it will page down, while using the controller it brings up the info screen. Try using the different ABXY buttons and see if that nets you a page up or down from the remote.scooby_dooby said:wow this update is really great, they pretty mnuch nailed every last thing that had bothered me, even little things like remembering where you were in a list after watching/deleting a video, you used to have to scroll down each time.

...and yeah, my music has been playing from screen to screen and game to game, the downloads keep letting me know when they are starting, pausing, finishing, its a helluva lot easier to find stuff. The scroll speed of my 80GBs of music is hot knife through butter fast now, the only time I see the "searching" icon is when I choose Artist, and the files are actually played in their correct order now.
A couple more changes like letting me know which downloads are incomplete, or when I go into memory to look at what to delete, how about telling me what the hell it was that I hadn't finished, that would at least be a clue to what I haven't finished d/l, as it stands now it just has some generic term like "Video something or other" nMB, but that a minor complaint.
Bottom Line from me: Two Thumbs Up
EDIT: Oh yeah, wtf is up with the deletion presses...I mean that should have been streamlined, we only have a 13GB hdd and E3 pretty much blew that outta the water for me.

Ya I noticed that a couple of the face buttons are labelled as page, but in the dashboard they seem to act as the actual buttons, I didn't realized they paged in Media Extender that's pretty handy. Which reminds me:
- why do my downloads stop when I enter MCE??
btw: sorry I didn't get around to returning your message, Table Tennis rocks!!! I haven't played it nearly as much as I should, but I went online a couple times and man was it intense.
Most definitely not. I see a big difference between movie film transferred to DVD and videotape transferred to DVD on progressive LCD displays both on my PC and my 360, with the videotape source material exhibiting the familiar interlace tearing between fields.tcrews said:
...Something film transfer material don't show. And don't bother to try and explain my PC deinterlaces the video first before displaying it, because if that was the case then why would there be certain material that shows interlace artefacting but not other, and also, deinterlacing is a massively CPU-consuming task. I watched DVDs on my old AMD K6-3 system with an ATi Rage128 Pro vidcard using no more than 30% processor power. If it had to deinterlace in software too, that system would have been dropping frames left, right and center.

Your videocard assisted with the deinterlacing. You're just wrong. DVD was designed for 480i content. And that's all it stores to this day. The difference you see is between film and video content, which can cause problems if the DVD is improperly flagged, or in cases where film content was edited on video as was common with some TV shows.
Also, if DVDs stored progressive content then progressive players wouldn't require the hardware they use for progressive pulldown. It'd be a matter of reading the data and displaying the data, but we all know the good players have better deinterlacing chips.

Ok already, go make a new thread about whether DVD's are interlaced or not if you guys want to discuss it that badly.
tcrews said:Most definitely yes. DVD's are encoded at 480i.

Wrong.
Most NTSC dvds (usa) are encoded at 640x480i & 29.97fps. Those dvds are interlaced, but it's easy to retrieve the 23.97 progressive signal (inverse telecine).
Most PAL dvds (europe) are encoded at 720x576p & 25fps. Those dvds are encoded progressive. Some of them are interlaced but they have crappy quality and most of them are confined to low-cost dvds

There's a great primer on the subject and explains all. What you're seeing is poor video deinterlacing or poor handling of badly encoded video material. Either way its still interlaced and exactly the problem that i was wanting to correct by offering native DVD output. While you see these artifacts on your current setup, a better deinterlacer would avoid them on most all video material (e.g. products with the DCDi logo are still among the best on dealing with video material and the jaggies/artifacts that accompany it).
You must not have been paying attention, Rage128 class vidcards do not have deinterlace assist. Even those that do only offer it in DVD players with direct support for it, and/or if you have specialized software installed (Nvidia purevideo f.ex, which is a costly extra, not included when the card is bought).Brad Grenz said:

I'm not. 480 rez = NTSC. We use PAL over here. Please stop speaking in such absolute terms, the US != the entire globe. Thanks.

If youre still contesting that DVDs are natively progressive, then sorry to say, you are.

PAL is 576i, but "i" nonetheless.
