so you look in the caps viewer undern HAL->Adapter Formats->Texture Formats
and
D3DFMT_P8
is listed?
and you used CheckDeviceFormat at runtime to verify before creating the
format?
and have a fallback if paletted textures are not supported?

do you have unmanaged debugging enabled?
you need that before managed-dx will propagate the debug info into the debug
output pane of VS when running under the debugger. or DBMon in the SDK. or
tools out on the internet like at sysinternals.com
you did read the doc section on "Tips and Tricks using Managed
Code->Debugging DirectX Applications?
if not, I suggest you need to do some reading. in both the managed docs and
the C++ docs.
given debug output is part of Windows and debug Windows, this is all basic
Windows development and not rocket science. the debug runtime output is the
single most valuable tool available to DX developers. use it.
