I applied the underscan portions of the patch but was wondering if you tested
and needed the overscan portions applied or if you just added those to make
them agree with the underscan lines. I didn't seem to need the two overscan
lines patched and in fact when I did apply those two lines it appeared to
break the video in the EPG when I had overscan turned ON. I also applied
the spelling/wording correction as well. If it appears the overscan portion
does need to be applied to work on your system let me know because maybe the
problem lies elsewhere instead of those 2 lines.
