Right, there are actually 4 different formats we are talking about - The AVI spec has a 1.0 and a 2.0 file header format, which is where the file size limit comes into play. The majority of programs out there use the 2.0 (OpenDML) AVI header format - the only exception I know of is the export function of an Avid. As far as DV Rack is concerned, all files written by DV Rack use the 2.0 (OpenDML) file header, and don't have the file size limitation mentioned.
Then, there are the different formats for DV data.
DV-AVI Type 1 puts the audio and video into one interleaved stream. It ensures that the audio and video will stay locked together, but some older editing programs will not read these files.
DV-AVI Type 2 store the audio and video in separate streams within the file. This makes it easier for some programs to open the file, but it can cause audio drift.
Unless your editing program specifically requires DV-AVI Type 2, I would recommend recording to the DV-AVI Type 1 format. What type of editing software do you use?
