what is the max. clip length for play mode 70 (PLAudio) - if any?

i can't play a movie with 01:38:00:00 length.

the movie stops (in PLAudio) at about frame 65536 wich is the known restriction if i would run him in play mode 2 (PLLoopFW).

the movie is converted from a DVD by MPEG Streamclip
at 25 fps and with AIC codec.

Q's:
1 - is there maybe a limit with the usage of a v4 XPress dongle.

2 - does the audio track of the movie need to have a special format.

the movie does not have any TC information.

thanks for your help.
