I have had an email back with answers to some fairly unambiguous questions from the technical support department of the manufacturer of the product discussed above. The questions relate not to the above product, but to an HDCP compliant DVI->VGA converter.

Can you please tell me if this device will allow me to convert from HDMI and/or DVI-D to an equivalent VGA resolution. I would expect to watch DVD's at 720p so I would like the VGA output to output 1280x720.

1. Can the DC-DA1 do this?
Yes.

2. The instruction manual mentions HDCP compliant. Does this mean that a DVD that has triggered HDCP encryption can be viewed at the same resolution via VGA? ie Bypass HDCP encryption.
Yes

3. Can the device handle both 60Hz and 50Hz source?
Yes.

4. If HDCP encryption can be bypassed, can the device be effectively disabled by the authorities by the transmission of a HDCP SRM. If it can be disabled, can it be re-enabled again by yourselves?
We use the same logic and parts used in HDCP compliant TVs. If our DC-DA1 will not work with HDCP SRM, almost all HDCP TVs will not work either.
To be honest, the answer to Q4 makes a mockery of the concept of device secret keys and system renewability messages used to revoke the device keys/non secret identifier (KSV). IMO, a single device being compromised should not affect other uncompromised devices.

Hopefully someone with a little more knowledge can enlighten us all.
