Many of you who have just purchased a PS3 and currently own a HDTV This is what happened:
All of you know that the PS3 is backward compatible and probly sold your PS2 when you got your PS3, then you pop in a PS2 game that does not support Progressive Scan (Now known from here on out as ProScan) and to your horror you learn it looks terrible. It is not your TV's fault or your games fault. This lies in a error that the PS3 causes. Here is what happens:
PS2 game running without ProScan at 480i

As you can see it is jagged and not smooth.
Now we take every other forth quadrent and cut it out.

Now lets flip the quadrent.
Put back into place.

It fits smoothly, AMAZING.
The problem is in two half:
1. The PS3 flips every forth quadrent and misplaces them. So any game running in 480i ON A HDTV will have these misplaced quadrents. Some PS2 games support ProScan. This enables the games to be in Progressive format. Such as 480p, 525p, 720p. It will say in the manual, back of the box, or in the options menu if a paticualr game supports this: Here is a list of all ProScan Enabled Games on PS2
http://en.wikipedia.org/wiki/List_of_Progressive_Scan_PS2_Games
If the game, such as Metal Gear Solid: Snake Eater does not support ProScan and only supports 480i then this firmware error will make the games look terrible.
Here is a larger example:
Running PS2 game on PS3 in 480i

Now the same game on the same system on the same HDTV only with ProScan in 480p

See the difference.

2. There is no scaler support for PS3 so basically this means the games can actually look better then they already do using ProScan. Most notably the 360 uses this so thats why some xbox games look better on the 360. Alos this scaller issue effects people with 480i/1080i HDTV's. Sony has stated it is working on resolving the issue.
(End of Speculational observations)

This is a serious problem and needs to be adressed, and to Gamespot members keep this thread alive till it gains a sticky status. The gamers need to know and this would end hundreds of pointless threads on gamespot. Thankyou this has been KaptainKernal.
MOD: Sticky please this is important.
