Adding metadata to FLV

[cblais]

We have a lot of previously recorded FLV videos on our site that never had any info/ metadata added to them. Now we're trying to find the best way to do it after the fact unfortunately. However part of the problem is that we don't know when it is done correctly.

This is our original XML file:
<duration>2901.287</duration>
<width>1280</width>
<height>480</height>
<videodatarate>150</videodatarate>
<framerate>15.0000152587891</framerate>
<videocodecid>2</videocodecid>
<audiodatarate>32</audiodatarate>
<audiodelay>0.075</audiodelay>
<audiocodecid>2</audiocodecid>
<canSeekToEnd>true</canSeekToEnd>

And then this is the beginning of the file after using a metadata injector:
<duration>2901.419</duration>
<lasttimestamp>2901.394</lasttimestamp>
<lastkeyframetimestamp>2901.362</lastkeyframetimestamp>
<videocodecid>2</videocodecid>
<audiocodecid>2</audiocodecid>
<audiodelay>0.075</audiodelay>
<canSeekToEnd>true</canSeekToEnd>
<width>1280</width>
<height>480</height>
<videodatarate>150</videodatarate>
<audiodatarate>32</audiodatarate>
<framerate>15</framerate>
<creationdate>unknown</creationdate>
<metadatacreator>Manitu Group FLV MetaData Injector 2</metadatacreator>
<metadatadate>1/6/2010 9:29:22 PM GMT-0500</metadatadate>
<xtradata>poker videos, sit and go poker video, PokerStars, free poker video</xtradata>
<videosize>107671020</videosize>
<audiosize>13439470</audiosize>
<datasize>26778</datasize>
<filesize>121137281</filesize>

The metadata we added is <xtradata>... Is this all that is needed for VSEO? Should we be worried that there is not a title or description or anything?

Thanks so much!

Does anyone know where I can find information on this?
