I followed a certain set of directions to try to make my XBox into a MythTV frontend and ditch my DVR service since it is pretty much cr@p, after doing so however, I can no longer log into my XBox via FTP and get the red light of death on each power on. I have posted the instructions below in hopes that someone else has had this problem or sees a way to fix this issue... thanks:
Both versions work in the same manner:
1. Find out the filename of your current dashboard (i.e C:\evoxdash.xbe for the Evox dashboard): That is the dashboard your Xbox is booting.
2. Rename your current dashboard to an alternate bootable name. This will be used as a fallback if execution of the new shortcut fails. Consult the table below, or www.xbox-scene.com for details on your dash.
3. Download the XBMC Shortcut XBE from the link above and rename it to whatever the dash was named (usually evoxdash.xbe)
4. Upload the renamed Shortcut XBE (i.e. evoxdash.xbe) to where the old dash was (Usually the root of the C: drive). The Shortcut XBE is now effectively your dashboard(!)
5. Install XBMC as a regular application to somewhere on E: or F: (for example, E:\Apps\XBMC) (Instructions on how to install XBMC can be found under Installing XBMC as an Application)
6. Create a text file on your computer with the same name as your renamed Shortcut XBE, except with the extension .cfg instead of .xbe (i.e. evoxdash.cfg) and put the path to the installed XBMC\default.xbe inside it (eg. E:\Apps\XBMC\default.xbe)
7. Upload the text file you just created to the same place you uploaded ShortcutXBE to in step 4. You should now have two files in your boot dash location. If your previous dashboard was Evox, These files will be named evoxdash.xbe and evoxdash.cfg. The .xbe is the shortcut XBE you just uploaded, the .cfg is the text file containing a path to XBMCs default.xbe
Congratulations, now you are all set and don't need to alter the shortcut again, unless you change location of XBMC's default.xbe.
* Please note that step 2 is optional. The actual fallback order is BIOS dependant. If you dont know what BIOS you are running, you're at risk. First try the xbe given by the .cfg file. Otherwise, the following filenames can be tried. But, the safest backup is to create a bootable rescue disc with a ftp enabled dashboard on it. See xbox-scene.com for details.
