I understand what you are saying, so I will "play around" with the problem and see if I can come up with a solution. Thanks again...oh, by the way I do have the latest up-to-date Cyberlink PowerDVD 8 (I just checked their website). Well, as I suspected you were absolutely correct. I was using RipBot264 to convert a 45GB Blu-Ray to a 23GB MKV file which I then reconverted to a Blu-Ray using tsMuxerGUI. The end result was a 1920:1080 movie which played fine on PowerDVD 8, but after using ImgBurn the end result was a movie with an improper aspect ratio. I reviewed the procedure and found that the resultant MKV was in fact 1920:816, yet when I converted it back to Blu-Ray with tsMuxerGUI it said 1920:1080 again. So I changed the PROPERTIES (Boxes)in RipBot264 to RESIZE to 1920:1080 instead of selecting DO NOT RESIZE (even though the input was a true 1920:1080 and selecting DO NOT RESIZE should have kept it as such and not changed it to 1920:816). I also selected DO NOT CROP (in the CROP box)instead of AUTOMATICALLY (which is what was recommended) and I now have a perfect 23GB version of the movie with proper 16:9 aspect ratio which I was able to properly burn with ImgBurn onto a BD-R. Thanks for steering me in the right direction.

Thanks again for your words of wisdom, but the strange thing is that playing the raw m2ts file gives me a movie with the proper 16:9 aspect ratio, whereas playing the ImgBurn created Blu-Ray or ISO results in a distorted aspect ratio with the vertical component stretched (the width is the same when I play either the m2ts or ImgBurn-created Blu-Ray and ISO discs...i.e., no clipping horizontally). So that seems to be the opposite of what you are stating above.

Actually CyberLink PowerDVD 8 can play back a single m2ts file by selecting "Open Media Files" in the drop-down menu. By selecting the one largest file (about 20GB)and playing it the movie can be viewed. This is not true for all movies, many of which are made up of numerous m2ts files so playing just one may only let you view a small part of the entire movie. Clearly a BD disc or ISO is the proper way to view the entire movie as you point out in your response. Thanks for your efforts and I will search other forums as you recommend.

Hi mmalves: I'm confused with your "thumbs up". I am not sure if you are telling me to mess around with my source files, because then I'm not sure what that means exactly...how can the source files be at fault if they play perfectly on Cyberlink PowerDVD 8, but the direct burn by ImgBurn or the conversion to an ISO by ImgBurn creates the same aspect ratio "distorted" video. Any suggestions about how to mess around with these source files? Thanks!

Thank you for the advice. I used ImgBurn to convert the source files (which play perfectly on the Cyberlink PowerDVD 8) to an ISO file. I then mounted this ISO in Virtual Clone and when I tried playing that with Cyberlink PowerDVD 8, I got the same "distorted" video (at least as far as the aspect ratio is concerned). Any other thoughts?

I have just used ImgBurn for the first time today and ran into a problem. I have a "compressed" Blu-Ray movie which plays perfectly (16:9 aspect ratio) when I play it using CyberLink PowerDVD 8 on my computer, but when I burned it onto a Maxell BD-R 25 (ImgBurn reads it as a Ritek-BR2) using ImgBurn the log said that everything was okay, but when I try playing the newly burned Blu-Ray disc on CyberLink PowerDVD 8 the 16:9 ratio is clearly not present anymore with the video being stretched vertically. I checked to make sure that the "maintain aspect ratio" on CyberLink PowerDVD 8 was selected and it was. I burned 2 such BD-Rs, one at MAX speed and the latter one at 2X, but both have the same "improper" aspect ratio. Video and audio qualities are otherwise great. Any thoughts?
