Hey everyone, Ive been trying to brew this set up for awhile. What I have is this: LG 240Hz HDTV 47 Audio Receiver + speakers Power Mac G5 dual 2.0 Ghz - 4 GB Ram - 2x 1TB SATA drives - ATI x850 graphics card HDMI -> DVI cable and an Optical Audio cable to the receiver Remote system compatible with FrontRow The first issue Ive got is to get various movie formats to work on my G5, I have mostly .mp4 and .mkv videos with mixed quality, 720p seems to play fine no matter the format or player, but 1080p seems to be very hit or miss, especially if the file is over 5 GB and is MKV, video is choppy. Obviously FrontRow uses QT (Ill get to that later), so I used VLC to play my high quality stuff, but 1080p MKV files play horribly, Ive tried to convert these to mp4, but the quality seems to go down (with handbreak or MKVTools), Ive resorted to converting them to AVI but Ive heard this destroys audio quality. I guess my question with that is; is my hardware too underpowered to handle MKV or is the file container/codec/encoder just that buggy? My second question is with FrontRow, Ive heard about some app that allows it to use VLC as a media player instead of Quicktime, but any search that Ive done hasnt turned up anything. I like the interface UI of FrontRow, just Id rather use VLC then QuickTime to view videos. If this cant work, itll mean Ill have to better equip Quicktime to play videos, would you guys recommend Perian or find and install codecs separately?
