Default SWEET! Progressive Scan

sponsored links

Just saw posts on other forums about doing a simple Hex Edit of XBoxdash.xbe to make your DVDs play in Progressive Scan mode.

Open xboxdash.xbe in an hex editor
search for : C7 46 28 20 00 00 00
replace by : C7 46 28 40 00 00 00
your Dash is now in progressive mode only
Tested on a 3944 dash.
Enjoy !!!

Edited :
For those without a DVD dongle, a little patch for DVDRegionX 2
83 C8 02 C1 E0 04 -> 83 C8 02 C1 E0 05
et voila it's progressive too.

Progressive scan can be used with HDTV monitors which support 720x480p which is the native format of film based material. The advantage of this is that the DVD MPEG-2 data stream contains flags which indicate the order of interlaced fields that make up the progressive frames.

In the case of NTSC video a 24 frame per second film source is converted into 60 interlaced fields using a process called telecine. The neat part of this process is that the inverse telecine procedure can be applied if you know which field goes with which frame as is the case with film based DVDs. This allows for TRUE progressive frames to be reconstructed from the interlaced fields and this yields a MUCH better image on larger and higher performance displays.
