Hi, ill start off by sayin hello and give you a little run down on what im trying to achive i have just attempted my first blu-ray to mkv i achived this by following this link but i have a couple of questions that id like to ask. http://www.recipester.org/Recipe:Rip_Blu-ray_to_MKV_files_19862345 the video i was converting was Inglourious Basterds BluRay. my main goal was to not touch the the video ie keep the same quality as the source i.e Blu-Ray 1080p & not worry about output file size. i converted the DTS HD audio as per the link but i only seem to get audio out of my centre speaker? (on a 5.1 system) my amp is this one in the link below i connect via optical(SPDIF) & i no my amp can decode the following pro logic 2 & DTS Neo 6. why could it be that the audio is only like stereo and not 5.1? http://www.denon.co.uk/site/popup/index.php?Pid=256 Second qestion thats bugging me is i followed the settings in the link at the top of my post to convert my BluRay to Mkv but when it came to ripbot i set the Kbps to around 8000 (i carnt remember the actual value but the one above 6367) Does that make the end result better picture quality because i used a higher Kbps? (also didnt use the resolution shown in the link as that is 1280x720 i went with 1280x1080) and thirdly when ripbot was chomping away putting the audio/video together the bottom status text showed the following 220091 Frames 10.26fps 8384kbps (obviously the fps were changing) but the qestion i have about this is, does this fps here just display how may fps ripbot is doing at that current time, or is it displaying what the end result will be becuse i thought higher fps was better? slightly confused! Thanks Guys/Girls Look Forward to lean more in this field of Knowledge Adam.
