Forgiveness if this is a bonehead question.  I'm trying to capture some HDV media from miniDV via a SONY HVR-M15U deck.  It was working fine yesterday.  Today, when I bring up the Capture tool, it asks me what tape is in the deck, displays timecode, and gives me full control of the deck.  However, when I choose the channels to record, it tells me there's no input signal present.  Any ideas?

I run Avid Media Composer 3.0 on an HP xw9300 Workstation w/ an AMD Opteron 252 dual processor, 3 GB RAM, Windows XP and an nVidia Quadro FX 5400 graphics card.

Have you set your project format to a HDV compatable format?

In capture dialog box, choose the correct Res,default may be Dvcpro HD,change it to HDV
