LFG4 Freezes

[samsc]

hi all, i'm new at this forums, hi richard, i really enjoyed your presentation!! very funning and necessary info! thanks, and what a beautiful soft (btw).

We (theatergroupAmsterdam) working with two of these cards in one quad 3 ghz mac pro, with specially desinged software (by ryan parteka) for control of 6 ptz cams and 3 more cams. we grab 8 composite video stream at once, which isn't a problem. we do this in a 6 our marathon theater show called Roman Tragedies.

The LFG4 cards are good cards and do what the should do. When we where testing (day-in-day-out) and building the show we had allot freeze issues. Because we where swapping bnc inputs on the cards they freezed more than now. When a freeze occurs we have to reboot the mac. So we build the system in a case, and still we find freeze issues. Very few and but totally unpredictable, what make the show unstabile.

We received new cards from active sillicon two weeks ago. Swap the old cards without any problems and we did 4 shows of 6 our run with success.

yes. there do seem to be occasional freezing problems.
you say swapping the cards made this go away?

yes swapping cards: that is: new cards from active sillicon. they made new cards with better interface chips to transport data from card to mac pro...

what we also did is start up the 'expension slot utility' and booth under a wrong setting off lanes, and later put it back to the original setting. but this was only to actived the cards... because the freezes are so unpredictable i couldn't tell wether this made a difference...

and yes, i invite you to our show... in march and june 2008 we play in hamburg, and vienna... so if you are in the neighborhood... drop by


cheers karl
