Revert "removing lowres support"
There have been multiple user complaints about loosing this feature
while its not clear the 3% speedloss claims where real or fabricated.
My own testing indicates no statistically significant speed difference
both with mpeg2 and mpeg4, and if at all the code with lowres support
is a tiny bit faster than without.
This reverts commit 92ef4be4ab9fbb7d901b22e0036a4ca90b00a476, reversing
changes made to 2e07f42957666df6d7c63a62263b8447e97b1442.
