update: i applied this microsoft patch which supposedly fixes firewire problems for xp sp2 users. http://www.microsoft.com/downloads/d...displaylang=en
after uninstalling the device and re-detecting it, this time i was able to select 6412 from the list.
i've tried capturing some recorded programs. but the resultant .ts files are unplayable in media player classic. they'd either not play, or play but stuck at 0 seconds, and there's no video even though sometimes audio can be heard. i've tried both HD and SD recordings.
