No. Not unless you've got the actual source tapes... or whatever they use nowadays.
If you've got, say, a DVD copy of Rambo: First Blood or so, you can't take the .vob, blow it up to HD size, and expect to get HD quality. No program is smart enough to calculate that stuff perfectly.
But most modern HDTVs nowadays (not to mention the PS3 itself) have built-in upscalers that'll automatically blow up an image to fit the screen, be it a DVD movie or something that's 654 x 232.
i was watching the original version of home alone 2 and it does not fill up the screen. I played it with my ps3 and nothing. I got black bars on both the left and right sides. Is there a way to make it fill the entire screen?
DVDupscaling is essentaily, guess work.
Upscaling/Upconverting DVD players contain a scaler, which allows the user to convert lower resolution content into a signal that the display device will handle as high definition content. Depending on the quality of the scaling that is done within the upscaling/upconverting DVD player, the resultant output quality of the video displayed may or may not be improved. The idea behind upconverting DVD players is that when a DVD player is connected to an HDTV, especially one of the fixed pixel display type such as LCD, Plasma display, or DLP and Lcos projection TV, scaling happens anyway, either inside the player or inside the TV. By performing the scaling closer to the source inside the DVD player, the video scaler gets to work with the original signal without the concern of transmission error or interference. There exists independent benchmark test[1] verifying that some upconverting DVD players do produce better video quality. However, remember under no circumstances will an upscaling/upconverting DVD player provide "high-definition content", since video information can only be retained or lost in each successive conversion step, but not created.
The black bars you refer to are actually part of the screen, as this is how the director wants you to see it.
You can use ZOOM on your TV, but you will be missing apart of the screen.
Another option is to rencode the dvd, cropping out the black bars, a lenghtly process.
Sudds, I think it actually is just the DVD being in Fullscreen ratio instead of Widscreen.
If that's the case, then you can always set the PS3/TV upscaler (or aspect ratio, it might be listed as that on your remote) to Fullscreen mode, meaning it'll stretch/shrink everything to fit onto a 16x9 screen.
The problem with this is that your Fullscreen DVD (which has a 4:3 ratio) will look like it's stretched horizontally. People will look fatter and stuff like that.
The only way to not have this effect is to get a Widescreen version of your DVD. The Widescreen version has, instead of a 4:3 ratio video, a 16x9 video, which will fit perfectly onto your TV (though it might have bars on the top and the bottom, but this is a common occurrence).
