You're all awesome. I know it seems a little strange. We started with the 900. We're recording lectures. Recorded with it for a while then the lecturer wanted to avoid needing a microphone. The BZ100 will record w/out the mic but only in NetMD not HiMD and won't connect to PC. The people who sold it to us didn't say and we didn't think to ask. (Honestly Sony stinks for creating such incompatability across one platform.) So when we put the NetMD disc into the 900 to download to PC we we're in for a bit of a surprise. Obviously we're back to recording on the 900 but we have too much information on other discs to just let it all go. If you have any other tips please include them. Thank you for taking the time. Very cool of you all.
