droped frames in recording.

[nitrogen_widget]

I’ve searched the forums but can’t seem to find my particular problem using a decent system & a hardware encoder.

I’m probably not using the correct terms so I aplogize if this was covered in another thread.

I’m running a sapphire theatrix 550 on a 1.67 ghz athlon XP with windows xp sp2. 512mb ddr ram.
Latest drivers are installed.
The crappy cyberlink software was on there but I uninstalled it & I’m using the mpeg codec from windvd 7.
I’m recording shows off my tivo at high quality & while the picture is very clear & sharp, it seems like I’m dropping frames when I record.

The CPU isn’t tanking & I have everything recording to a second HD that has been defragged. It doesn’t matter what quality I use.

The slight jumps in the picture make my eyes buggy. I tried playing the file through GBPVR & on another PC using cyberlink powerDVD & I’d say it looks like maybe every 4th or 5th frame is being dropped.

I’ve cut back on the non-needed services & do not have much running at boot up either.

Does anyone have any ideas?
