Let’s please keep the facts straight… there is a lot of confusing information here…
1.) Only Xpress Pro HD and Media Composer Adrenaline HD can deal with FireWire directly.
Meridian has a FireWire card option, but does not work in 24fps.
2.) All versions of Media Composer since 1992 can deal with 24 frame capture (NORMAL) and manage the 24fps and 30fps timecode as well as 25, 25fps with pulldown, etc.
3.) Xpress Pro and Media Composer Adrenaline can capture both ADVANCED and NORMAL pulldown over FireWire or s-video, component, SDI, etc.
4.) Media Composer Adrenaline 2.1 and Xpress Pro 5.1 can capture NORMAL pulldown over FireWire in addition to ADVANCED
5.) Xpress Pro HD 5.0 can output either ADVANCED or NORMAL over FireWire, no need for Mojo.
Xpress Pro HD and Media Composer Adrenaline HD introduced the Canon XL2 deck template since the camera did not exist before that time. Try using a generic NTSC template.
Your mail did not specify whether the DV material was shot NORMAL or ADVANCED. If NORMAL, you can use any system dating back to 1992 to work at 24fps. You can capture over analog or SDI (not FireWire). You need to log or capture on timecodes ending in 0 and 5. All material shot on these cameras at 24fps is always non drop (unless you male a dub to a drop frame source. In which case the Avid have always had the ability to capture 24 from a drop frame source as easily as a non drop source.
If you Meridian system does not have a 23.976 project, you need to capture your audio over analog out. The pulldown switch will be set to .99 in software when capturing audio that is referenced to NTSC.
Hopefully this makes things clearer… 😉
