Subject: bttv in 2.2.18 worse than 2.2.17

With 2.2.18, I've noticed a few problems with my Hauppauge Win/TV 401
(bt878) card not present in 2.2.17 (using XawTV 2.46 in overlay mode for
both):

1) Switching channels causes a brief flicker where the picture shrinks to
1/4 the size in the upper left corner, then changes to the next channel.

2) JPEG captures cause a purple and green fuzzy screen to briefly flash in
place of the television image.

3) The first time I run XawTV after loading the module, I get no picture
until I change Television -> Composite -> Television.  Subsequent runs are
fine.

Video card is an S3 Virge DX.

Just changing the array value back to 3 that was flipped 3->4 in the 2.2.18
patch doesn't do anything by itself.
