Ok, since we see a lot of people posting questions and comments regarding burning HD DVD firmware images into the main firmware threads, I figured I'd start a new thread for this topic alone and have the mods make it a sticky. That way, people can use this thread as a disk burning resource/guide and we can keep the main firmware threads free of redundant posts.

Basic Firmware Burning Tips
1) Remember to unzip the image file (If required) before attempting to burn it! - In some regions, Toshiba zips up the firmware image files, so be sure to unzip it before you attempt to burn it to disk. The disk extension that cd burning apps will expect for ISO image files is '.iso'. If the file you download already ends in '.iso' (Not '.zip'), no further action is required before burning it onto a disk.
2) Burn disk as ISO image only! - Attempting to burn the ISO image to a cd as a data file will not work. If your cd burning application does not support ISO burning (Many trialware versions of cd burning apps don't), then download one of the apps shown below.
3) Use cd's only! - Toshiba does not recommend using blank DVD's to upgrade their players and you may brick your player if you do use this format. You've been warned.....
People (Myself Included) have had good experience using Memorex cd-r blanks in both the HD-A1 and HD-A2 players. Other brands may work just fine as well, but YMMV here.
4) Set the burn speed to whatever you're comfortable with - Many folks recommend burning sensitive data like this to disks as slowly as possible, to avoid screwing up the disk and burning a coaster. I personally have burnt working firmware disks at speeds of 16x - 32x, so this advice is not set in stone however. I'd recommend using whatever speed you normally burn other data at.
Nero
http://www.nero.com/enu/downloads-ne...b936c93f7f51d6 - (Nero 10 Trial version)
1) Fire up Nero Burning ROM and select 'CD' or 'DVD' from the dropdown menu. Then click on the 'ISO' tab. This should bring you to the screen similar to the one shown below (May differ slightly based on the version of Nero used). Adjust your settings to match what is in the image, then click on the 'Open' button, browse to the HD DVD firmware ISO file, and then click 'Open', to open the image.
2) You should now be on the 'Burn Compliation' screen. Adjust the 'Action' checkboxes to match those in the image below, then set the write speed to something you're comfortable with. Many people recommend changing this setting to the lowest possible speed, but I've burnt working firmware disks at 12x speed and up, so your mileage may vary here. Finally, make sure the 'Write Method' drop down is changed to the 'Disk-at-once' value, then click on the 'Burn' button to burn the image. This should produce a working HD DVD firmware upgrade disk.
DeepBurner
http://www.deepburner.com/download/DeepBurner1.exe - (Free version)
1) Launch Deepburner and select 'Burn ISO Image' as the project type as shown below.
2) Browse to the Toshiba ISO file using the radio button to the right of the 'Image File:' file path input area. Once the file has been selected, (As shown in the screenshot below) set the desired 'Write speed' and click on the 'Burn ISO' button to burn the firmware image.
Active ISO Burner
http://www.ntfs.com/downloads/Iso-burner.exe - (Freeware)
1) Launch Active Iso Burner and browse to the path of the Toshiba ISO image by using the radio button to the right of the 'ISO Path:' file path input area. Once the path has been selected (As can be seen in the screenshot below), click on the 'BURN ISO!' button to burn the firmware image to disk
NOTE: I was personally unable to burn a firmware disk using this application as it caused my computer to lock up completely every time I clicked on the 'BURN ISO!' button. So be warned! However numerous other AVS Forum members have reported burning disks using this app with no issues and it appears to be the simplest app to use out of the ones listed above, so give it a try (Save all work first!)
