MJPEG Tools Svn

MPEG-2 encoding with non-progressive DCT in progressive streams and
interlaced streams now fixed and working again. Numerous small code
hygiene improvments. Minor performance increase (no generation of
reference data for B-frames unless statistical logging is turned on.
MPEG-2 multiplexing options in mplex made sane.

update code

v4l interface

first pass at getting v4l interface for python

first command for tuners

first attempt at getting direct-tv guide

Reverted debug mod in readpic.

Silly error in write(2) usage causing sporadic errors fixed.

Restored at least basic progressive sequence/ frame_dct MPEG-2.
The interlaced stuff is currently horribly broken and requires
attention.

Also a small tweak to mplex to make the audio a little more conservative.

Final tune of coefficients.
