Just Got AIW 7500... No dropped frames, but video is jerky.

[unclebok]

I am a bit new to all this... I just picked up an ATI AIW 7500 card, and am trying to get some decent TV captures going here.

I have resolved my frame dropping issues, but the videos I am capping are turning out jerky, in many places.
I am using basic settings from Ati's MMC, Like "Good", "DVD", "Longer", and even "VCD".

I'm not sure what other info would be helpful.

Is this a common issue? I'm hoping I just need to tweak a setting somewhere that I am unaware of.

I have the AIW7500 on one of my machines and I have found out that the MMC software that comes with it is not all that good...

I scrapped the software and went to a Pinnacle software product.... can't recall off the top of my head... something like PCTV or something like that... It gave me better capture ability...

There are other tv tuner/capture software packages out there as well...

I have an AIW 7500 running under Win XP and I can cap 352 X 480 48 KHz stereo audio with Huffy AVI compression with few if any frame drops on my PIII 1 GHz and 7200 rpm capture drives. Best way to go rather than to cap to Mpeg-2. Use Virtual Dub and set Record Master as the input under XP. You can use the ATI software if you're capping off TV for timeshifting but the capture is way inferior to capping in AVI then encoding to your final format. What are your computer specs? That sometimes gives us a clue as to what your problems might be...

Thanks for the replies.

I'm gonna try some more stuff out on my own before I go bugging y'all for more help with capture problems.

For statrers, I'm gonna pick up a seperate hd for capture. My current drive is a 40 gig 5400rpm drive with only about 20 free gigs on it.
I'll pick up a 7200 rpm drive and grab up some more ram

current PC stats are something like this:
Windows xp
900 mhz athlon
40 gig 5400 rpm hd
192 ram (sdram i believe)
AIW7500 vid card
... I dunno what else is important...

thanks again.
