Question: No HDMI I have an older TV that doesn't have a HDMI outlet. It has a DVI. Will the Roku box still work with it? I want to run movies to my TV from Netflix through my Mac computer.
Document: I received my Roku XDS in a matter of days. Very quick service.I have an older TV and DVD that uses RCA cable (supply your own HDMI cable if you have newer equipment). However, if you still want to use your DVD player as well as the Roku device, you will need an additional RCA splitter or cable as the package only supplies a RCA cable (red/yellow/white three male heads each end) to connect from Roku directly to your TV.
Overall, I'm pretty satisfied with my Roku. The setup was fairly easy, although I had to run up and down the stairs from the TV room to my computer several times. The streaming over my wireless network seems to work pretty well, too, although in my house the Roku box is less than ten feet from the wireless router.One thing that I am disappointed is the availability of streaming content. There's quite a bit of stuff that I'd like to watch that just isn't available for streaming.
I bought this to replace a Mac mini-based entertainment system (the Mac mini again assumed the more traditional role of a computer in replacing an older desktop). Everybody loves the Roku now. Although Netflix was also used with the Mac mini, the Roku seems to make it easier and more approachable for everyone.
But, if you want HD, as I do, you will need to purchase an HDMI cable or Component Video/Optical Audio cables separately. This is clearly spelled out in the, "What's in the Box", info so it was not a surprise. However, if you have an older "non-HDMI" TV or receiver and need a Component video cable you will need to get it from Roku because the connector on the Roku end is non-standard.
I have an older HD TV without HDMI input. This box had the most output options that would work with my TV as well as USB input. Only downside is the older Roku boxes like this do not receive the PBS channel and i sorely miss that.
I've had this little box for a couple weeks and watched ten or so movies without any problems whatsoever. The package arrived on time and in good condition. Setup went fast and smooth. I purchased this exclusively to stream Netflix.I use it with an older 37" 720p/1080i Vizio TV through HDMI, a $25 TP-Link wireless G router, 5 Mbps Comcast connection, and a low end Yamaha RX-V365 receiver through the optical connection, all with cheap Monoprice cabling.
Both the Netflix movies we tested showed a "four star" quality rating. The box is currently connected to the TV via the included RCA jacks. I will order an HDMI cable to see if that improves the quality. It is already much better than when I have streamed movies directly on the computer.UPDATE:  I installed the HDMI cable (12/28/2010) and found the picture much improved.
Received Roku XDS 3 days ago. Hooked it up to Sony Wega 480 P 36 inch CRT downstairs since I didn't want to run up and down the stairs to check router settings.Could not get it to connect to wireless. I use the mac address to filter out who can connect to my wireless network. Checked and double checked. It would not connect. Fortunately I have Netgear Powerline device HDX111 that allows me to use our power outlets as a network. Hooked it up to that and was off and running.
No more cable bill for me. It's the greatest thing to watch any show you want when you want. This little box streams movies instantly to your TV from Netflix and several of their own free channels. It has built in wireless internent and you don't even need a computer.I don't miss my sattelite TV and their expensive monthly charge one bit. For $14.99 per month I have Netflix on two TVs and enjoy all the shows and movies I want.
I picked this over the apple TV because it included the RCA hookup where the apple one is only HDMI, this makes it possible to use on older TVs and when I travel. It set-up very easy and I have no no problems using it with my netflix and MLB accounts. Although I wish the footprint were just a little smaller, I still think its great.
Answer: We use a Roku HD with an older TV which has composite inputs (red, white, yellow) and it works great. Part of the Roku setup will ask you  questions that address this and other things.  It was a snap to set up.  With Roku you will not need a computer except to register the Roku.  You can manage your Netflix queue on your Mac if you want. You can also use the Roku on your TV.I think you'll like it.
