Here are the symptoms. The Live TV feature in GBPVR is jumpy, playing about 3 fps on average, even though recordings come thru nearly perfect. DVD playback (in any program) is also slower than I recall with occasional jumps in the video. When I set up a large mpeg file, say 2 hours recorded in mpeg 2, for conversion to xvid, the program I use (xmpeg) takes forever to load the file initially (5 gigs or so), sometimes more than 5 minutes. Processing of said file progresses at about 5fps.
The same programs on my laptop work without a problem, and at least the DVD playback used used to be fine on my desktop. Benchmarks (via FreshDiagnose) between my laptop and desktop are comprable in terms of CPU and multimedia capability. However, my desktop is old, and while it has twice as much RAM, it's antique 60ns stuff. I also have a wussy s3 prosavage video card. My computer is firewalled (Zonealarm), AVGed, and regularly scanned with Ad-aware. I recently did a thorough cleaning of the registry. As far as I can tell, everything should be tip-top.
DivX and Xvid files play without a hitch in any player.
Processing(with the same settings/codec--XviD) of the same files on my laptop as mentioned above with the same programs averages at more 20fps, with seamless loading of even massive mpegs. Live TV works with no problem as well. As far as I know, I have the same extra codecs installed on both computers: xvid 1.0x, Divx 5, ac3, et al.
Off the tops of your heads, can you guys tell what might be the issue? Why does it take the mpegs so long to load and why do they process so slowly, what makes livetv so shakey? They seem like related issues, and it is my hope that it isn't hardware related. Any suggestions would be appreciated.
