Just bought Die hard 4 and wanted to rip it to the hdd and then convert the main feature to mkv to add to my hdd collection playable through win mce. The ripping process worked ok with the latest anydvdhd then I took the m2ts containing the main feature 00020.m2ts and remuxed it into an MKV using gsdemux ... but the resulting file does not play well. The video is very jerky (when using powerdvd h264/avc filter codec) with some weird artifacts in the image ... if I turn off the purevideo accelaration in the filter the artifacts are gone but play back is very slow ans it almosts seems like the PC can't handle it (PC is high specced core2duo which can handle anything thrown at it) I normally also can play m2ts files directly from the hard disk using kmp player or powerdvd but the same video problem occurs - so the problem is not with the mkv remuxing. When I play the film directly from the disk it plays ok in powerdvd. Tried both the latest powerdvd and 3319a. I am aware that this is a BR+ title but I thought that oncce the files are ripped and if the directory structire of the DVD is preserved you can at least be able to play the files in powerdvd ?? Anyone has a detailed suggestion on how I can play this title directly from the hard disk with normal looking video ?
