I've been dealing with a lot of MXF files recently, specifically the widespread (and irritating) 1080i XDCAM HD422 variety. To be specific, I want a 20 second piece out of the middle of a 4 minute MXF file created by an XDCAM camera. Is there a good solution to convert and  trim piece of MXF to ProRes with 8 channels for post production?

For those who are curious, XDCAM HD 422 is essentially Long GOP MPEG-2 using 4:2:2 chroma subsampling. The flavor I'm using is 1080i 60, at 50mbps CBR. It's pretty good quality, and usually comes with 8 audio channels of 24 bit, 48 KHz AES style PCM. A lot of free / open-source tools, including MKVMergeGUI, VirtualDub, QuickTime Pro, etc can perform trims when it comes to MPEG PS, MPEG TS, MKV, MOV, AVI, etc. But as to MXF, there is such issue being regarding trims and concatenations.
