For the original ms dashboard, open xboxdash.xbe in a hex editor:
Search for: C7 46 28 20 00 00 00
Replace with: C7 46 28 40 00 00 00 (Progressive only)
Replace with: C7 46 28 00 00 00 00 (Auto-selection)
For dvdx-2, open its default.xbe:
Search for: 83 C8 02 C1 E0 04
Replace with: 83 C8 02 C1 E0 05 (Progressive only)
Search for: E0 10 0B F0 51 8B CF
Replace with: E0 10 0B F0 51 EB 71 (Auto-select)
Also, search for: 5E C2 18 00 90 90 90 90 90 90 90 90 90 90 90
Replace with: 5E C2 18 00 80 61 28 9F 8B CF E9 84 FF FF FF (Auto-select)
* You need to search for and replace both hex strings to make dvdx-2 work in auto-select.
Things to take into consideration:
When typing in the hex values to search for, try typing in the values without the spaces if you are having trouble finding the strings. For example: for the ms dashboard, search for C7462820000000.
Auto-select supports both 480i and 480p. If your TV supports progressive scan, it will display it in 480p. If it does not, it will display it in 480i.
The ms dashboard, and DVDx-2 hex edits are independent of one another; you can just hex edit the ms dash, or just the DVDx-2, or hex edit both of them.
The dvdx-2 hex values are only for dvdx-2, not dvdx-1. Dvdx-1 is just a patch for the ms dashboard/dvd playback that enables region free dvd. Its progressive hex values are the same thing as the ms dashboards.
Make sure you make a backup copy of your original xboxdash.xbe, and progressive hex edit the copy. Then after you are done hex editing it, call it something like pxboxdash.xbe. Then put both the original xboxdash.xbe, and the progressive hex edited pxboxdash.xbe back in the root of your c: drive. And change the xboxdash.xbe, in your dashboards (evox, avalaunch, unleashx, etc.) to pxboxdash.xbe, so it will recognize it. Having both the original xboxdash.xbe, and the pxboxdash.xbe in your c: drive will allow you to turn off your mod chip; the original bios will only recognize the the original, unmodded xboxdash.xbe.
All dashboards (AVA, evox, unleashx, etc.) and apps (xbmc, emulators, etc.) show up in at least 480p, while many support 720p and 1080i without having to hex edit it for progressive scan.
Also, credit goes to ProgScan for most of these hex edits. He is a member here at xbox-scene and on xboxhacker.net. Credit for the dvdx-2 auto-select goes to viperman3, a member here at xbox-scene.
