Live TV a Little Choppy and Sound Crackles

[StueyDNubey]

Hello all

My htpc is a little choppy during viewing live tv and the sound is slightly crackly. It seems to record and playback the recording just fine.

Is this a normal thing or is there something I can do to fix this.

My system specs are:

MB: ASUS P4GE-MX
CPU: Celeron 2.53Ghz
RAM: 512MB
VC: Nvidia FX5200
Capture Card: Hauppauge PVR-150 MCE
OS: Windows XP Media Center Edition SP2
PVR Software: GB-PVR (latest version)

I tweaked the OS for a little more performance by disabling unused services and disabling Media Center from running.

Some things I was going to try tonight were a better video card, I have a ATI 9800 Pro.

Also, could it be a inefficient codec? In the config, my playback decoders are all set to system default.

Does anybody have any suggestions to get Live TV to perform better.

Thanks in advance.

Also, my Sound card is a older Creative SB PCI 128. I may try the onboard sound card tonight.

Thanks
