[vdr] Re: OSD Memory

[Jeremy Jones <mr.lebowski@gmail.com>]

Where did you get the 90kb number from ?  Its not that I question the
number but just curious how it was obtained.  Also, do you know what
actually determiens how much memory is given to the OSD ?  I'm
wondering if it would be possible to increase it.  What I'd really
like to do is create a 720x240x4bpp window and another 360x240x4bb
window (roughly 126KB).  I suspect the firmware is responsible for
managing this memory so I'm guessing this is possible without
modifying the firmware (I'd also like to avoid soldering on the extra
SDRAM :-)).

Thank You,
bball
