what will I need to do the following

Hi, I'm way over my head hear and after reading many posts, reviews and information I'm no closer to my goal.

Below is my current setting, what I want to do and what I think that I will be purchasing. Please let me know if I'm on the right track or if I need to do something else.


Current setting

Vizio 1080p 47 lCD HDTV
Sony PS3
Dishnetwork vip622 receiver
Yamaha DD receiver

what I would like to do
- Connect my PC directly to the LCD TV via hdmi, component or vga to get 1080p support
- play hd and blue ray dvds
- capture video from my Sony HD camcorder and play it on the TV
- capture videos from my old mini DV tapes to the hard drive of my pc and play them back on the lcd tv
- view all my photos on the tv
- backup some of my dvds to the pc hard drive or external hd and play them back on the tv
- somehow to be able to take the video out of my DVR and back it up to my PC (just as if I hook up a vcr to my DVR). I'm not looking to replace my DVR here, just to be able to record or back my shows while I'm watching them. This way I will not run out of space on my DVR.
- browse the internet and play youtube and other video on my tv
- move the ps3 downstairs and use a smaller TV and then stream content to the ps3 to be played back on that TV

I'm thinking of purchasing HP media center desktop with the following
Windows Vista Ultimate (32-bit)
Intel(R) Core(TM) 2 Quad processor Q6600 (2.4GHz)
4GB DDR2-667MHz dual channel SDRAM (4x1024)
512MB NVIDIA GeForce 8500GT, TV-out, DVI-I, HDMI
Wireless LAN 802.11a/b/g/n & Bluetooth(R )
500GB 7200 rpm SATA 3Gb/s hard drive
Blu-ray writer / HD DVD player & Lightscribe SuperMulti DVD burner
15-in-1 memory card reader, 2 USB, 1394, video, audio
ATSC-NTSC TV tuner with PVR, FM tuner, remote

well, am I way off here or do I need to look into another direction? any help is much appreciated.

Thanks

Thanks Davdev. Yeah, I know that I wuill need to do more research about what I'm looking for.

As for the HD size, yeah I thought about that too and I'm hoping that in the future I will build a NAS to store more digital content on it.

If there are more suggestions please let me know.
Thanks

Thanks Allin4greeN. I was going to get for my VIP622 but the fees imposed by dishnetwork did not sit well with me.

So is there away to have the video/audio out from my TV to be recorded on my PC?
I used to do this with my DVD player/burner before it died on me. So what I want to do is to record what ever I'm watching on my TV screen to my PC.
If anyone know if this possible, please let me know and what is the best way.

Cheers

bulls, do you recommend any good encoder card? Thanks

just to clarify one thing, I want to be able to take the S out from the DVR and capture the video to my PC. Is this doable and what is the best capture card to do it with?
Thanks
