Trying to capture video from a Sony dcrtrv730 via
firewire. On both PCs (one is 600 P3, other is 1.6 P4),
MM recognizes and controls the camera, but when I try to
preview or record, the camera acts like its cycling from
play to stop and the capture is beyond poor. Does anyone
have any suggestions?

Try turning off all other apps, inc internet/a-virus/firewall/screensaver

Defrag hdd.
Ensure plenty of space, 13gb per hour.
If no luck, try windv, which is purely for capturing and exporting video.

At the risk of going off-topic,
I followed your link, but figured that windv was not appropriate for me
as I have only fairly rudimentary equipment: Sanyo analogue camera,
Adaptec AVC1100 USB capture box.

I have been getting audio and video progressively out of sync, perhaps
especially, I suspect, after trimming the beginning of clips.

I have tried a variety of software to do the capture and concluded that
the progressive loss of sync is due to dropped frames (during capture?).

However, <http://windv.mourek.cz/> contains a link to VirtualDub,
<http://www.virtualdub.org/index>, which I have downloaded and
installed.

After discovering that, for VirtualDub, it was necessary to route my
audio signal through line-in on my sound card, rather than through the
Adaptec device, it is now capturing both signals successfully.

The point of my post is that this is the first piece of software I have
encountered that actually tells me how many frames have been dropped
during capture, a most useful piece of information.

I shall implement the usual advice as above, then further testing will
determine if I can overcome the loss of sync.
 
Windv is for dv capture not analogue, so you are right in it not being
useful for you. Sync of audio/video is often a problem unless you use
quality equipment which has a way of locking the audio/video signals.
Depending on how much you are doing, have a look at canopus or miglia
equipment, reviews here
