The Humax software download page is http://beta.humaxonline.co.uk/
It no longer lists the 9200T. Version 1.00.23 dated 20 May 2010 is likely to be the last version and not be broadcast again.
If you have an older version (e.g. 1.00.21 with its remote issues) then 1.00.23 can be downloaded via a PC from www.myhumax.org one of the UK Humax users' independent sites. (The other being www.hummy.tv currently down for maintenance.)
You will need to become a member of that forum to download version 1.00.23.

If you have previously not manually update a 9200T the forum can also advise on two (Humax and an unofficial) software programmes either which can be used to update your 9200T with the 1.00.23 software.
