I have downloaded the official release 1.0 of Vorbis from vorbis.com and I also got the latest compiles (21/7/2002) from dailyVorbis(http://www.inf.ufpr.br/~rja00/ogg.html). Which one should I use? I noticed that the oggenc.exe is 1 Mb in the official version and 250kb in the daily vorbis version...Is it ok to use daily vorbis?

Because UPX is used for compress.

The one that pleases you most.

Dailyvorbis from RareWares is faster, but some people prefer the warm fuzzy feeling of using official binaries. (Both are compiled by the same person, BTW, but with different compilers)



The files at RareWares are compressed with UPX.
http://upx.sourceforge.net

There's no noticeable performance hit when using files compressed with UPX.



Yes.

If you have some reason for the larger file, you could download the UPX ( http://upx.sourceforge.net ) and there is an option to decode the file. I am not quite sure why you would want this though...

And especially if there could be, it happens only at load time

must explain this
