DVDxDV Violates GPL

DVDxDV converts MPEG-2 files from VOB format (DVD) to DV video. One of their major features is decoding AC3 audio into high quaity 16 or 24 bit audio. The first evidence for the violation is circumstantional and suspicious. DVDxDV is an internet company and no contact information listed on their site. When I contacted support to ask about the violation, they did not respond. Their domain name is registered using Network Solutions "Private Registration." Why all the secrecy, DVDxDV? Finally, we all know the only AC3/A52 decoder out there is released under the GPL. The privacy is because they know they are violating the GPL. Take a look at these strings which are found both in the DVDxDV v1.083t Mac OS X binary and also the ac3dec-0.6.1 source code. I ran the "strings" command on DVDxDV, then for each string, grep through the ac3dec source code. The result shows the file and line number of strings common to both DVDxDV and ac3dec-0.6.1:
DVDxDV-strings.txt:22:"(-3.0 dB)"
        ac3dec-0.6.1/libac3/stats.c:50: {0.707, "(-3.0 dB)"}, {0.595, "(-4.5 dB)"},
        ac3dec-0.6.1/libac3/stats.c:56: {0.707, "(-3.0 dB)"}, {0.500, "(-6.0 dB)"},
DVDxDV-strings.txt:23:"(-4.5 dB)"
        ac3dec-0.6.1/libac3/stats.c:50: {0.707, "(-3.0 dB)"}, {0.595, "(-4.5 dB)"},
DVDxDV-strings.txt:24:"(-6.0 dB)"
        ac3dec-0.6.1/libac3/stats.c:51: {0.500, "(-6.0 dB)"}, {1.0,  "Invalid"}
        ac3dec-0.6.1/libac3/stats.c:56: {0.707, "(-3.0 dB)"}, {0.500, "(-6.0 dB)"},
        ac3dec-0.6.1/libac3/stats.c:51: {0.500, "(-6.0 dB)"}, {1.0,  "Invalid"}
        ac3dec-0.6.1/libac3/stats.c:57: {  0.0,   "off    "}, {  1.0, "Invalid"}
DVDxDV-strings.txt:26:"off    "
        ac3dec-0.6.1/libac3/stats.c:57: {  0.0,   "off    "}, {  1.0, "Invalid"}
DVDxDV-strings.txt:27:"R   "
        ac3dec-0.6.1/libac3/stats.c:157:char *exp_strat_tbl[4] = {"R   ","D15 ","D25 ","D45 "};
DVDxDV-strings.txt:28:"D15 "
        ac3dec-0.6.1/libac3/stats.c:157:char *exp_strat_tbl[4] = {"R   ","D15 ","D25 ","D45 "};
DVDxDV-strings.txt:29:"D25 "
        ac3dec-0.6.1/libac3/stats.c:157:char *exp_strat_tbl[4] = {"R   ","D15 ","D25 ","D45 "};
DVDxDV-strings.txt:30:"D45 "
        ac3dec-0.6.1/libac3/stats.c:157:char *exp_strat_tbl[4] = {"R   ","D15 ","D25 ","D45 "};
DVDxDV-strings.txt:31:"(syncinfo) "
        ac3dec-0.6.1/libac3/stats.c:121:        dprintf("(syncinfo) ");
DVDxDV-strings.txt:32:"32 KHz   "
        ac3dec-0.6.1/libac3/stats.c:126:                        dprintf("32 KHz   ");
DVDxDV-strings.txt:33:"44.1 KHz "
        ac3dec-0.6.1/libac3/stats.c:129:                        dprintf("44.1 KHz ");
DVDxDV-strings.txt:34:"48 KHz   "
        ac3dec-0.6.1/libac3/stats.c:132:                        dprintf("48 KHz   ");
DVDxDV-strings.txt:35:"Invalid sampling rate "
        ac3dec-0.6.1/libac3/stats.c:135:                        dprintf("Invalid sampling rate ");
        ac3dec-0.6.1/libac3/debug.c:38:   env_var = getenv("AC3_DEBUG");
Now, isn't that a bit much for coincidence?

Boycott DVDxDV!

Spread the word: DVDxDV has stolen GPL code and they don't deserve to prodit from it. Email and tell them to come clean! Either they release their source code, or the remove the ac3dec code.

It uses other GPL'd libraries too. I had at one point contacted the copyright holder. He wasn't interested in pursuing them himself. If you're interested in going after this guy, contact me.

Please read the following Announcement in its Entierty and
Consider the Possibilities
Watch this One to Trade!

Because, EGTY has secured the global rights to market
genetically enhanced fast growing, hard-wood trees!

EGTY trading volume is beginning to surge with landslide Announcement.
The value of this Stock appears poised for growth! This one will not
remain on the ground floor for long.

Keep Reading!!!!


-Energy and Asset Technology, Inc. (EGTY) owns a global license to market
the genetically enhanced Global Cedar growth trees, with plans to
REVOLUTIONIZE the forest-timber industry.

These newly enhanced Global Cedar trees require only 9-12 years of growth before they can
be harvested for lumber, whereas worldwide growth time for lumber is 30-50 years.

Other than growing at an astonishing rate, the Global Cedar has a number of other benefits.
Its natural elements make it resistant to termites, and the lack of oils and sap found in the wood
make it resistant to forest fire, ensuring higher returns on investments.

the wood is very lightweight and strong, lighter than Poplar and over twice
as strong as Balsa, which makes it great for construction. It also has
the unique ability to regrow itself from the stump, minimizing the land and
time to replant and develop new root systems.

Based on current resources and agreements, EGTY projects revenues of $140 Million
with an approximate profit margin of 40% for each 9-year cycle. With anticipated
growth, EGTY is expected to challenge Deltic Timber Corp. during its initial 9-year cycle.

Deltic Timber Corp. currently trades at over $38.00 a share with about $153 Million in revenues.
As the reputation and demand for the Global Cedar tree continues to grow around the world
EGTY believes additional multi-million dollar agreements will be forthcoming. The Global Cedar nursery has produced
about 100,000 infant plants and is developing a production growth target of 250,000 infant plants per month.

Energy and Asset Technology is currently in negotiations with land and business owners in New Zealand,
Greece and Malaysia regarding the purchase of their popular and profitable fast growing infant tree plants.
Inquiries from the governments of Brazil and Ecuador are also being evaluated.


The examples above show the Awesome, Earning Potential of little
known Companies That Explode onto Investor�s Radar Screens.
This stock will not be a Secret for long. Then You May Feel the Desire to Act Right
