Youtube high quality?

[lnminente]

Good to see activity here

Some testing:
+If we add &fmt=22, mp4 file, stereo sound ~232 kbps (at least in the video of dancing Matt) If not available the quality will be the standar flv.
+If we add &fmt=18, most of the time the video will be an mp4 file, with good quality, stereo sound ~130 kbps. If not available the quality will be the standar flv.
+If we add &fmt=X&fmt=Y the quality will be X

If we set fmt=22, and its not available, it's very probable there is a mp4 for fmt=18, but we will see the standar quality, so at this moment it's not a good idea to use fmt22.

The web filter needs more work. It $SETS variable \5 each time proxomitron avances one character. Also it uses too much cpu, the number of $TST for each page is too high only for this filter. It's better to make the filter fail before using $TST.

One question for the header filter, what's the reason for using ! instead of URL:?
