Yes, just have a button that does page down (PgDown).  If you are
using lirc, you can also adjust the autorepeat settings so that it
will go faster.  This is what I have in my ~/.lirc/mythtv file for my
MCE USB remote:

begin
    remote = mceusb
    prog = mythtv
    button = KEY_AGAIN
    config = PgUp
    repeat = 1
    delay = 2
end

begin
    remote = mceusb
    prog = mythtv
    button = KEY_NEXT
    config = PgDown
    repeat = 1
    delay = 2
end


It is also possible to customise the theme so that you can once again
go up to go to the bottom of the list.  To do that, you copy the theme
from /usr/share/mythtv/themes to /home/<mythtvuser>/.mythtv/themes.
Then rename the new theme directory eg I changed MythCenter-wide to
MythCenter-wide-JSW.  Change the theme name also in the themeinfo.xml
file.  Then do any other changes you want to the new theme.  Finally,
in mythfrontend, go to the theme chooser and choose your new theme.

I did the patches Zig worked out for this problem:

I think the first of those patches is the one you want.  The second
does the same thing to the right hand side of the recordings screen,
but there is a bug in how it works so when you delete a program that
is in a list that is longer then one screen, it all gets rotated up
one program invalidly.  So you might not want that one unless you are
sure the bug is not going to be a problem for anyone in your
household.

The third patch brings back the display of the end time for
recordings.  I find that extremely useful also.
