Home audio & video: Blue Ray from a PC drive
Blue Ray from a PC drive
by javra - 4/24/07 3:13 PMMy PC is sitting next to a Samsung 46" LCD and I just added a Sony BD-R drive. My PC utilizes the full resolution of the LCD which is 1920*1080. I am using Cyberlink PowerDVD to watch Blue Ray movies and I can expand my view to my whole screen but I have no idea if I am getting full 1080p or some sort of scaling. The quality is very good and everything looks much better than DVD but I could be fooling myself. Anybody have any ideas how to find out?
Cyberlink PowerDVD, dose a very good job of upscalling!
by jcrobso - 4/25/07 8:09 AM In reply to: Blue Ray from a PC drive by javraPower DVD upscales to resolution that the video card is set to.
Even if you are watching a standard DVD they look really good on a PC.
Try watching a standard DVD using your PC and compare.
I have WMV encoded HD DVDs they will play at 720p or 1080p on my PC, I have 47" CRT-RP, It is very hard to tell the difference between 720p and 1080p, may be if I had 72" I could tell the difference.
So far you are the first one that has posted using a B-Ray DVD in a PC. John
Upscaling
by javra - 4/25/07 9:25 AM In reply to: Cyberlink PowerDVD, dose a very good job of upscalling! by jcrobsoI have actually compared DVD and BR playback with PowerDVD before posting on this forum and the BR discs look much much better. Unfortunately I do not have the same disc in BR and DVD to compare so it had to be with different titles. From what I have read about AACS and HDCP some titles will automatically downrez if all the DRM requirements are not met. So still even though my eyes can tell the difference and my display can do full 1080P and the BR titles all say 1080P on the cover, I am not sure I am getting that.
"AACS and HDCP some titles will automatically downrez"
by jcrobso - 4/25/07 11:34 AM In reply to: Upscaling by javraThere was a big uproar two years ago about this because HDMI was new and not widely implemented. Most Studios said they would not turn on the d-rez bit in the HDCP, at least for a few years.
What resolution is your PC set to? John
1080P

uh oh
by masterying01 - 4/26/07 11:20 AM In reply to: Upscaling by javra" I do not have the same disc in BR and DVD to compare so it had to be with different titles" You wouldnt have this problem if you had HD DVD.
OOOOOOOOOOOOOOOOOH *Throws a punch at blu-ray*. FEEL FREE TO FIGHT BACK.
but back to the topic. what kind of computer you running? (graphics card, monitor, etc). i was under the impression that most graphics cards out there do NOT support HDCP which is something that is needed to play Blu-Ray movies in full 1080p. if it doesnt support HDCP, like john said, your computer would downgrade that to the "regular resolution" and your cyberlink program would pump that back up through upscaling.
Theory
by javra - 4/26/07 1:11 PM In reply to: uh oh by masterying01I understand full well that if everything is HDCP compliant I should be getting 1080P.
This is not helping answer the question though. Let me put it this way: If I have an HDCP compliant graphics card how to tell if I am getting 1080P when using PowerDVD on a PC screen that happens to be a 46" 1080P capable TV? And the answer cannot be: Well your setup is good so you should be getting it! 
1.3 hog wash and Amps with vidio pass thru .

No receiver
by javra - 4/25/07 4:57 PM In reply to: 1.3 hog wash and Amps with vidio pass thru . by stewart norrieMy PC is connected directly to my TV which has both DVI and VGA, so there is no receiver involved. The sound goes through optical out to the receiver.
DVI can be HDCP complient.
by jcrobso - 4/27/07 7:59 AM In reply to: No receiver by javraPower DVD, which version??? Windows Media player, Power DVD and other programs use Direct X to control the video card and they can change the resolution on the fly. I don't know if Power DVD even looks at the down res bit. John
Version
by javra - 4/27/07 9:01 AM In reply to: DVI can be HDCP complient. by jcrobsoThe latest version of PowerDVD. From what I remember 7.2 or 7.3
JAVRA, YOU MIGHT ALSO, WANT TO ASK ONE OF THE PC FORUMS.....
by Riverledge - 4/25/07 5:17 PM In reply to: Blue Ray from a PC drive by javraAND HEAR WHAT THEY THINK. The wonder of these "FORUMS" is that there is so much sincere advice, freely offered in all topics; thanks to C-NET.
Best wishes,
