I think HTPC was the best category for this, given that I'm not actually sure what component is the issue...
I'm a college student bored in the summer and trying to prove to my parents that high definition actually IS pretty cool. Anyways, I've got an old Compaq Presario S5300NX from 2003 hooked up and am trying to get it to do things it was never intended to for kicks. Specs that matter:
Intel Pentium 4 2.5 GHz
1024 MB Ram
Windows 7 32 Bit.
All drivers are up to date.
Remember we're talking 2003... IDE, DDR1, straight-up PCI, and all those other great standards of yesteryear.
Just yesterday I stuck a GeForce 9500GT with 1 GB memory in the thing. It's a straight PCI, which I'm pretty sure negates any speed the 9500GT offers, but whatever. I have not replaced the sound card yet, so it's the good old integrated Realtek.
Now my problem: Video playback sucks.
No matter what the source, it is choppy. Youtube, DVD, files, anything. Not just high definition material (which is VERY bad), but standard as well. No audio problems, but the picture is jerky.
I use VLC for everything not online, and all of my files on the computer are MKV containers, mostly either MPEG2 or H.264. I have tried adjusting preferences including caching sizes, video outputs, etc. Some things help but do not solve the problem. Disabling audio entirely seems to help quite a bit. Task manager would suggest the CPU is not the issue, although that seems like it would be a bottleneck... Anybody got any ideas??
I can give more details upon request! Just trying to keep this post to a short story as opposed to a novel.
