I shot the whole range of remote codes at my Toshiba HD DVD player yesterday with a Pronto and thought I'd share my results with you guys. I have an European HD-XA2 (HD-XE1) but reading from Internet I think many of these codes work for other Toshiba HD DVD players as well, perhaps HD-A1 and HD-A2 as well as HD-E1 at least?
Apparently the Tosbiha HD DVD remote code is using some NEC format which in short-hand (that is supported by many universal remote controllers) looks like this:
900A 006D 0000 0001 45B5 xxxx
Where the last xxxx is formed of two hex numbers that total FF when added together. Like the first code is 00FF where 00 I think is the actual function and FF is a checksum. This means that there are 256 possible remote codes ranging from 00FF to FF00.
This is all my conjecture, so use at your own risk, but see this thread on RemoteCentral.com for some insight into this and also on the subject of how to convert the NEC1 protocol short-hand above to a longer format if your remote requires it:http://www.remotecentral.com/cgi-bin...?keywords=3704
The most important remote code, of course, that could be gleaned from all this is the discrete off (play could be used for discrete on):
- Discrete off: 900A 006D 0000 0001 45B5 936C
- Edit... Discrete on? 900A 006D 0000 0001 45B5 FE01
But I also found some interesting maintenance codes in the Cxxx range. Trying this though, I'd recommend being very careful and avoiding e.g. the code ending with xx3A. That starts some kind of update process apparently saying don't shut down. It accepts no remote commands (it shows the remote code pressed on player's screen though, which is interesting), no powerdown but is fortunately exitable by pressing Eject on the player - or at least was for me, I'm not trying that one again... Whew. Some other codes also produce error messages on video or on player screen.
These codes I found to do something interesting:
- Player display test, all the items in the player display light up and animate: 900A 006D 0000 0001 45B5 C738
- Disc tray lock (for all you folks with kids) on and off: 900A 006D 0000 0001 45B5 C639
- Time and date on players screen (sorry, only for a moment): 900A 006D 0000 0001 45B5 CB34
- Factory reset (you loose all your settings): 900A 006D 0000 0001 45B5 CD32
Edit: VoTT made this interesting discovery:
i found discrete code for output HDMI resolution according EDID:
900A 006D 0000 0001 45B5 C43B
works during playback
I tried it too and it actually does toggle between all the modes (480p, 720p, 1080i60, 1080p60 and 1080p24) on my set during playback, although it will prompt that it restarts the movie at least when moving from 480p to 720p.
- Perhaps the coolest, version/revision information screen: 900A 006D 0000 0001 45B5 CF30

Except on mine it says HD-XE1 something on the first row and I guess some of the other numbers are different too, I don't recall.
Also the codes C936, CC33 and CE31 produce firmware etc. version information that is displayed on player's screen.
These are the codes how they worked on my HD-XE1 (which is like HD-XA2). I can't guarantee they'll work the same on your machine or other models.
I do wonder if some of the maintenance codes could be used to help bricked players. OTOH, toying with the maintenance codes might brick your player so try at your own risk and please be careful.
I'm sorry I'm no remote code expert so this is the extent of help I can offer, others at RemoteCentral.com might be able to so try that.
