1080p video encoding

[morphinapg]

If anybody here has some video encoding skills can ya help me out? I would like to encode 1080p content that I have captured off of my DVR in the standard MPEG2-TS format. I would like to compress them using DivX HD, WMV-HD or any other HD codec. I have tried DivX 6.4 using the 1080HD setting at 6 Mbps and WMV HD at 8 Mbps and both tend to play as if the audio is playing perfectly fine but then the video plays at like half speed, greatly affecting sync. I use a 1.8 GHz AMD Athlon 64 3000+ 1.5 GB RAM, GeForce 7950 GT 512 MB and Sound Blaster X-Fi Platinum. I have been able to run 1080p quicktime and WMV-HD video files I have downloaded off the internet (such as movie trailers) just fine but whenever I make them myself I run into the above problem. If someone experienced in this could help, I'd appreciate it. I will soon be upgrading to a AMD Athlon 64 X2 4800+ (within a couple months) so then this problem likely won't happen at all, but I'd also like to allow users with my kind of specs to be able to play my 1080p videos as well.

what is wrong with mpeg2 ? With hard drives so cheap, why recompress?

Well, each 1 hour show I record at MPEG2 are about 6.5 GB, that's a lot. I can get those shows down to about 1.25 GB at 720p. I never notice a loss of quality at that bitrate either.

I dont think the time it takes to encode is worth it.... as I have over 2 TBs of stuff I recorded off of cable.

I just simply set it to encode before I go to work and it's done when I get home

Just do whatever you want to do.

Ram seems ok but you definately need a faster processor if you u want to do any HD stuff my friend...not sure if that is causing ur problem though, but you should be around 3 ghz if you are working with HD material.
