I would get errors on long sequences or sequences which stradled the 00:00:00:00 timecode (midnight with TOD TC). Toggling the Playlength command fixed this issue. Haven't tried on Interplay though.

Dealing with long, stop and start style reality tv clips is a big pain in the arse in Avid. Multicam is miles behind where it should be at this point.
What we do is:
Auto sequence each camera for the day and then build a master sync map from these auto sequences so you have one sequence with Camera A on v1, Camera B on v2 etc. Check they are all in sync with each other. I'm not worried about audio at this point.
Once you have the sync map, show your reference clips and make sure any in or out marks are cleared. Find the first bunch of overlapping clips in the timeline and park the play head at the start of the clip that starts latest in the section. Select just the video layer of this clip. Match frame to place an in point on the clip in the bin. Select the next track and repeat until you have done all the tracks and placed in points on all the reference clips for that section. Now group these clips by in point.
Go to the earliest clip in the group and cut the newly created group over the top of the sync map. Keep doing this for the sequence and you'll end up with a sequence just made up of the grouped clips of your sync map. There's usually a few stray clips which couldn't be or shouldn't be grouped so i just move them out of the way or make the executive decision to delete them if they have no value to the edit. This is a much faster way to group than the popularly expounded technique found on the web;
which lends itself to endless mistake-making and frustration.
Once you've grouped, you shouldn't have to worry about the 24 audio track limit as I can't think of any cameras that record this number of tracks. Normally you'll only have to deal with a max of 8 tracks from any given camera in the group or possibly a few more if there was an external sound device used.
I'm not sure if this is of any help or if it's clear? If you'd like, I can do a screen grab step by step for you tomorrow when I'm at work so you get a better idea of what I'm talking about as we have a few projects that have required us to use this kind of grouping.

Marian,
I just finished posting a performance series for PBS where we recorded many long continuous clips of 4 hours 49 minutes each, using multiple Cinedeck MX machines recording DNxHD 145 in MXF OP-Atom wrappers, including 4 channels of audio per clip. All our clips play flawlessly on multiple Avid MC 7.0.4 systems running on a Windows 7, on hardware ranging from a Dell quad-core i7 laptop to an HP Z800 dual hex-core Xeon machine.
And after reading your post I just strung together 3 clips of 04:49:00 each and, as you noted, I couldn't play the audio. But then I went back and cut shorter clips together into a sequence of 13 hours 20 minutes and the audio plays fine. (HP Z400, Win7, MC 7.0.4).
So yeah, I did replicate at least one of your bugs. But I can play clips of over 4 hours, and a sequence of over 12 hours, with audio.
Cheers from snowy Boston,
Wilson Chao

Hello everyone
One of our customers just begun production of a reality show, where they film some folks around the day.. something like BigBrother. They are using MC with interplay to edit the material but we've hit some limits that makes the editors life very hard :
1. They use "Autosequence" to line up in sequence all the clips, recorded with time of the day as TC. That is a nice feature, but unfortunately those sequences cannot be used in a multicam group. We;ve tried the "Autosync" on those sequences to create a subclip, but it;s not working since there are edits in it. (not sure what edits are, since there is no cuts, trims etc)
As a workaround you must do videomix downs on those clips, but this is insane since the it takes a lot (they have 8 or 9 cameras, and the resulting clips are around 18 h per day.
Is there any other way that you can use those sequences for multicam? I
Is it true that Premiere can do it?
2. Seems that we've hit a bug where sound records longer that 4 hours are not played in MC, Import is fine, but you cannot get any audio out of MC. Waveform is also blank. As a result you need to split the audio in smaller files
3. Initially they planned to have one sequence per day where they can have all the material in. But we've hit 2 limitations: If a sequence is longer than 12 h, you will not get any audio out, even if waveform is there. You need to split the sequence to monitor audio tracks. Also you cannot have more than 24 audio tracks, in MC 7. or 8. In MC 5 you can have more that 24, but only 24 active
How do people deal with those limits? I would assume that others hit those issues before us.. maybe they have a solution
Thanks
Marian B
