UNCOMPRESSED Digital Audio Tips

With blu-ray disc players and uncompressed HD audio you’re going to find that the “digital coax” and “fiber optic” will only transmit standard “Dolby Digital” and “DTS”. You will NOT hear uncompressed when using these connections.

HDMI connection or 7.1ch AUDIO OUT supports UNCOMPRESSED Digital Audio transfer.

(When using an HDMI cable, make sure your “HDMI Digital Audio Out” in your Blu-ray Disc player’s setup menu is set to “Bitstream” and not “PCM”.)

The “dts-HD Master Audio” is the best, followed closely by the “Dolby TrueHD”. The “Uncompressed PCM” is leaps and bound better than standard “Dolby Digital” and “DTS” but not quite as good as the other two HD Audio formats.

Be sure to pick up the newer (and less expensive) PS3 “Slim” to get the best audio quality from your Blu-ray Discs.

The original PS3 would decode “TrueHD” and “Master Audio”, but down-converted both signals into “LPCM” before outputting them over HDMI.

The new PS3 “Slim” sends both “TrueHD” and “Master Audio” signals completely unchanged over and HDMI cable to your capable receiver.

Windows Registry Limits

Registry Element Size Limit
Key name 255 characters. The key name includes the absolute path of the key in the registry, always starting at a base key, for example, HKEY_LOCAL_MACHINE.
Value name 16,383 characters

Windows 2000:  260 ANSI characters or 16,383 Unicode characters.

Value Available memory (latest format)

1 MB (standard format)

Tree A registry tree can be 512 levels deep. You can create up to 32 levels at a time through a single registry API call.

Long values (more than 2,048 bytes) should be stored in a file, and the location of the file should be stored in the registry. This helps the registry perform efficiently.

The file location can be the name of a value or the data of a value. Each backslash in the location string must be preceded by another backslash as an escape character. For example, specify “C:\mydir\myfile” to store the string “C:mydirmyfile”. A file location can also be the name of a key if it is within the 255-character limit for key names and does not contain backslashes, which are not allowed in key names.
