DVD's are all in 480i format. Progressive Scan converts them or more correctly, de-interlaces them to 480p.
I hope this was just a typo.
Glossary of Terms
DVD TERMS
Anamorphic: The process of compressing widescreen images to fit into a standard 4:3 television screen size. The images are then expanded for viewing in their original format on a widescreen display device. To fill a widescreen TV, a non-anamorphic DVD must be expanded, resulting in loss of resolution and detail. A DVD that is anamorphic, or "enhanced for 16:9," delivers 33 percent more resolution than regular letterboxed transfers and does not need to be expanded on a widescreen set. An anamorphic DVD generally appears clearer letterboxed on a standard 4:3 TV because it does contain greater resolution.
Aspect Ratio: The relationship of width to height in a television set. Traditional Color Television product features a 4:3 aspect ratio. Widescreen and future HDTV products will incorporate a 16:9 aspect ratio.
Audio input: Jack(s) on the rear of a component, such as a receiver, or amplifier, or a recorder that connects using cables to the audio output of a source device (CD player, VCR, tape deck, etc).
A/V input: Jack(s) that connects to another component's output. Usually found on receivers, amplifiers, preamps, TVs, VCRs and other products.
A/V output: Jack(s) that connects to another component's input. Usually found on receivers, amplifiers, preamps TV’s VCRs and other products.
Component video: Elements that make up a video signal: luminance, which represents brightness in the image, and separate red and blue signals (expressed as either Y R-Y B-Y or Y Pb Pr). Component video signals are superior to composite and S-video images because of improved color purity, superior color detail, and a reduction in color noise and NTSC artifacts.
Composite video: The video signal combining luminance and chrominance, the burst signal and sync data (horizontal and vertical). A direct video connection using an RCA-type plug and jack; its signal quality is better than the RF type of connection but inferior to S-video and component video.
DTS (Digital Theater Systems): Film and video surround system that incorporates 5.1 channels. It can be built into an A/V receiver or A/V preamp, or purchased as a separate surround processor. DTS is well supported by hardware makers but not by software companies. Their process is available on only a few DVD and CD titles. Proponents believe the sound quality is superior to Dolby Digital, the most common source of surround sound.
IEEE 1394 DV input: High-speed digital video and data interface technology adopted by the Institute of Electrical and Electronics Engineers; For connecting digital television and computers to various components and peripherals, such as Digital VHS, set-top HDTV tuner boxes and digital video camcorders and DVD recorders.
S-video (Y/C): Higher quality video input and output than composite video connection that segregates chrominance and luminance signals for optimum reproduction from high-quality video sources such as SVHS, Hi8 and DVD players. Not as good as component video, but more common.
480i (interlaced): A form of standard-definition digital television (SDTV) that approximates the quality of analog television; not considered high-definition television (HDTV). Even though the native resolution of DVDs is 480p, they are viewed at 480i on an NTSC analog television
480p (progressive): A form of standard-definition television (SDTV) It is not considered high-definition television (HDTV), though it is noticeably cleaner and sharper than (SDTV) analog television. The native resolution of DVDs is 480p, however that resolution can be seen only with a DVD player that outputs a progressive-scan signal and a TV with progressive scan or component video inputs.
Dolby Digital: Digital multi-channel surround sound technology developed by Dolby Laboratories to encode films for theaters and home video; it uses a lossy compression technology to compress the digital audio soundtrack. Dolby Digital is the most common surround sound format used in DVDs and in DTV broadcasting. Dolby Digital is a 5.1-channel system with 3 speakers in front, 2 speakers in the rear and 1 subwoofer. Dolby Digital decoders are built into many newer A/V receivers, A/V preamps and surround processors.
