recording for projection??

[Anonymous]

I attended a groundbreaking yesterday for a new high dollar equity owned golf club that my office designed. The owner spent about
$30k to take my ADT building model & render the heck out of it then create video animations & stills for their marketing effort.
The video was created, then burned onto DVD with sound. The owner rented a tent, had 2 open bars, heat pumped in, food, etc - then
did the champagne bottle on the bulldozer trick followed by the gold painted shovel photo op with the new governor--- had invited
all the new club members & had 2 large projection screens set up.

Well the AV dude tried to play the DVD thru his projection systems and all we got was audio. He said "the DVD wasn't recorded for
projection". Well, the founders were steamed, the marketing girl was nearly in tears, and I just sat & wondered - you see because
the DVD played just fine on my $70 DVD player on my television (thru regular old cables). The AV guy failed to do a test run
prior... and to make a long story short they ended up hooking up a laptop w/ DVD player to the projector & it went well till the
video clip exceeded the notebook RAM capacity - then the (edited).

Has anybody had this problem, or can anyone confirm that a DVD needs to be burned in some different way in order to be played thru a
projector??

I'm assuming from your description that the "Projector" had it's own DVD
player. If so, it may not be compatible with DVD-R - similar to early CD
players and CD-R disks. But I don't know for sure.

What doesn't make sense is the laptop would choke due to RAM capacity. Was
it like only 64MB or RAM or something?

I hope the AV dude wasn't the guy who produced the DVD - otherwise he'll
have a hard time collecting that $30k. If he's just an AV service he's
probably only out a few hundred dollars because of his blunder of not
testing beforehand.

With money like that, they must have a web site - I'd be curious to look at
it.

A DVD doesn't need to be burned any different way for projection. It may
have been a few other things though that have nothing to do with the
projector. Most of them have to do with the DVD player and burning software
that you use.

1.) The DVD player may not support the particular flavor of DVD you burned
(DVD-R, DVD-RAM, DVD-RW, DVD+RW).

This doesn't sound right though, since you got Audio playing out of it.

2.) The Video Cable used may have been crushed/poor quality/otherwised
damaged.

Did the AV guy try to use another video cable to determine if this was the
problem?

3.) The DVD encoder you used may be a little on the cheap side.

DVD uses MPG2 as its compression technology, and there a lot of ways to
encode to MPG2 and not get DVD quality video. And DVD players have
different tolerances on their decoder, so one DVD player may be able to
decode it, while another may not. It varies greatly depending on the
manufacturer and the price range.

DVD audio on the other hand has only three, very fault tolerant, formats.
AC3 (aka Dolby Digital), MP3 stereo, or DTS. So even if the audio encoder
is terrible, chances are the decoder will pick it up.

So to sum up, the problem was most likely due to reason 2 or 3. And the AV
guy should have done a test run to see if those two were the problems. Any
AV techie worth his/her salt should check all the equipment in the
environment it will be used prior to the presentation. It's just common
sense.

Just my $0.02,

The player was able to output both audio & video to a standard television.
He insisted that "the disk wasn't burned for projection" - which just sounds
weird to me. Perhaps the projector had incompatible jacks - but wouldn't
all of them likely have red/white/yellow AV cable inputs?

Just to clarify, you took the same DVD player, with the same cables that
were on the projector, and used them on the TV. And you got a picture out
of one and not the other?

That doesn't sound right at all....

The "A/V" jacks are stereo audio and composite video. And composite video
has been standarized since the 40's (In this case NTSC).

It really sounds like something is wrong with the projector in that case.

Another question...

How did you connect the Laptop to the Projector? Via VGA or the composite
video connector?

Confused in CT,

I've had some problems with DVDs being projected. It's a weird thing. I can
see the player window, and hear the sound, but not see the video. Just one
of those things I've learned to accept.
