mvpmc page up/page down

[Mordechai T. Abzug-3]

[Is it best to report bugs here or to the -devel list?]

When I use mvpmc in either the filesystem or mythtv modes, there is an
odd bug when using page up/page down on multipage lists.  Suppose I am
on a multipage listing that currently shows items 1-10, and the cursor
is on item 4.  If I hit page down, mvpmc shows items 14-23.  This is
counter-intuitive -- mvpmc is skipping items 11-13.  What I expect to
see is items 11-20, preferably with the cursor on item 14, although
cursor elsewhere would also be fine.

I first noticed this bug in mvpmc 0.33.  It is still present as of the
20090621 snapshot.

That depends I think here since it might not be a bug

There was a commit to viewport settings quite a while back that I
didn't really like, so I just added a command line option --classic to
use the older style of calculating the size.  You might want to check
if that works for you.

I tried it.  The bug is still there.  

[Methodology: I added --classic to the mvpmc invocation in
dongle.bin.mvpmc.config, rebooted, logged in, and verified that
--classic was there via the ps command.]

Exact steps to reproduce:

(1) go into "filesystem" and into a directory with many entries.

(2) Make a note of the last entry on the first page.

(3) Press page down (channel down) and make a note of the top item on
    the second page.

(4) Press page up (channel up) and note that you are back where you
    started.  The last entry on the page should be the same as for
    step 2.

(5) Press next file (down arrow) and make a note of the last entry on
    the page (should still be same as for steps 2 & 4.)

(6) Press page down (channel down) and make a note of the top item on
    the second page.  Note that it is different than for step 3.  This
    is the problem; it should be the same as for step 3.

This should be fixed in the latest daily build

Thanks,
