I did some tests on VQEG sequences using IP Frames, then IPB bframes,
etc etc

The md5sums of the output streams were equal. So this new mbtransquant
is probably safe.

Example:
PMV_EARLYSTOP16 | PMV_HALFPELREFINE16 | PMV_EXTSEARCH16 | /* Q 6 */
PMV_USESQUARES16 | PMV_EARLYSTOP8 | PMV_HALFPELREFINE8

and

XVID_H263QUANT | XVID_HALFPEL | XVID_QUARTERPEL | XVID_INTER4V

I got this for foreman sequence:
$ md5sum stream-*
a6b17beb8c67ed72642ccf185fec8fbb  stream-new.m4v
a6b17beb8c67ed72642ccf185fec8fbb  stream-orig.m4v

Another one from foreman:

PMV_EARLYSTOP16 | PMV_HALFPELREFINE16 | PMV_EXTSEARCH16 | /* Q 6 */
PMV_USESQUARES16 | PMV_EARLYSTOP8 | PMV_HALFPELREFINE8

XVID_H263QUANT | XVID_HALFPEL | XVID_INTER4V

$ md5sum stream-*
e00843b451a59a32ddbbd1ae9a5abba3  stream-new.m4v
e00843b451a59a32ddbbd1ae9a5abba3  stream-orig.m4v

So if you find a clip where the raw stream is diferent, please tell
me. If nobody complains about bitstream differences then i'll commit
that this week end (probably saturday).
