I have downloaded irecord for my macbook pro and am running into some issues. I have been able to hook up to my comcast/motorola cable box via firewire and have even "recorded" a 5 min test clip. The problem came when trying to view the clip. The clip is in a .m2t format. Is this right? Do I need to convert the file to another format? I tried opening it with itunes and no luck. I acknowledge it could be a problem somewhere else in the process. Under the irecord preferences it says that my cable box does not have a "tape unit" but does have a "tuner unit". Could that be it? Can anyone with some experience with irecord for mac help me? Thanks.
