Hi Justin,

Yeah, it appears that the code is not able to detect the integrated TMDS
transmitter for DVI. (likely connected to DVI-D connector)
Since I do not have the actual box in front of me, it is going to be rather
hard to figure out how to get it working since the known detection method that
worked for my Sylvania g netbook's DVI (integrated TMDS) does not appear to
work for your box.
That being said, over the past month, I have rewritten DVI initialization code
so that it can support multiple TMDS transmitters (integrated and external) per
system.
I was able to create the code to support SiI 164 in about 2 hours since 98% of
the code is unchanged from VT1632 support code.
Please try Version 0.5.142 since Version 0.5.141 was a bad commit. (i.e., the
files to support SiI 164 were not inserted into the Git repository correctly.)
I do not have a box with SiI 164, so I cannot test the code myself at this
point.
I hope it works.
