Another 720p question

post #1 of 4
Thread Starter 
So I've been watching videos through my HTPC on my 24" tube TV through the S-Video cable...I mostly watch standard definition videos but when I tried to play 720p videos, it lagged like crazy. My HTPC is definitely nothing special, it has a 2.8GHz socket 478 P4 (no HT) with 512MB of DDR 266 and a Radeon HD 9700 Pro with 128MB RAM. So...i'm guessing the 9700 Pro is what can't handle the 720p? or would it be the RAM? Cause I have played 720p fine on the same processor in a different rig. If it is the Radeon HD, do you think a 6600 GT would be better? Cause the Radeon HD has 256 bit DDR memory while the 6600 GT has 128 bit DDR3 memory...Thanks for the help

Edit: Just thought of this...is the S-Video too old school to even stream 720p? Hmmm

S-Video is only capable of 480i. I would guess somehow that your HTPC is down-converting the 720p to 480i and that's what's causing the lagging.

Oh okay makes sense, thanks for your reply + Rep because I would have been swapping out graphics cards and you saved me lots of time and frustration. For future reference, is the 9700 Pro capable of playing 720p?
