Chrontel 7008
The situation: my TV-out equipped laptop (815EM chipset),
a TV set, an original, paid-for DVD and me. DVD works fine
on the small TFT but refuses to play on the big TV.
What's wrong? The TV-out chip of my laptop, a Chrontel
7008, doesn't support the output of a copy protection
(Macrovision) and thus the DVD player application simply
refuses to work! Man, behaviour like this REALLY ticks
me off. Therefore, instead of spending the next hours
viewing the DVD I patched the TV out part of the graphics
driver. I did this about 2 years ago, therefore I don't
remember the details. Anyway, here is the patch, the
DLL is still the most current version:
File to patch: Ch7xxNT5.dll, version 6.13.1.3196, file

Version 6.13.1.3198 is basically the same code but
needs a different checksum. Try patching only the last
3 locations and then use SetCSUM
on the result.
