Streaming DV to Harddisk choppy, why?

[karhooi]

I have Canon MV700 series DV camcorder, when streaming the DV to harddisk (Western Digital 200GB, 8MB cache) the video become choppy, but if capture to maxtor harddisk is OK. And when capture as MPEG2, is OK as well!

Maxtor 60GB - Master 7200RMP (NTFS)
Western Digital 200GB 7200RPM - Slave (NTFS)
Motherboard - i845 series.
Video - Geforce 2 MX

I suspect either the harddisk is faulty or not fast enough????

when streaming the DV to harddisk

I'll assume you meant transferring..

the video become choppy

Is this during playback or capture??


Since you don't have the specs on the board, i'll take a guess...
Just because your .AVI is playing back choppy, doesn't mean that you've lost any info, or have a bad video...
It's simply the result of a lot of computer power trying to playback a lot of information.
As far as MPEG playback is concerned, it's usually software assisted, thus resulting in smooth playback....

yes, transfering.
It's choppy during playback. The problem is if transfering to Maxtor harddisk it will be all fine!!
Motherboard is Asus P4XP-X P4 2.66MHz and 512MB DDR 266

Do you have DMA enabled for catpure for the problem harddisk??
Seems really odd..Since your DV is essentially digital, i'm surprised you'd be getting these problems. It's not like your capturing, converting, and then saving like you would with analogue video..

Unless you've got a 5400 rpm drive, i'm perplexed..We could get into Virus Scan dissabling, defragging, and partitioning, but i'm guessing you know your basics from the capture guides.

oh yes, DMA..i'll check on it. Anyway thanks pijetro!

Firstly i tried to format the harddisk with the cluster size 64K, hoping this could help in video transferring but end up with the choppy plaback problem, then i format again with default cluster size which is 4K but still no go.

I still blaming the WD harddisk because it have some problem with the partitions (missing) when i created.

Thanks again Pijetro!
