CASTLE  Loved Rivet, paid for it and it worked a treat with my router setup. Now I'm trying to get Rivet to work with my Xbox via sharing my Mac's internet with it. No dice. According to the Rivet forums this isn't possible with Rivet. But it is with Connect 360. Wasted $20. Well, I did use Rivet for a month or so, so not totally wasted, but if you want to share your Mac's internet with your Xbox you'll want Connect 360, not Rivet.

TAKN  Back to Connect360 I go.... Sorry Rivet

I originally switched from Connect360 to Rivet a few months ago. This was mainly due to stagnant development & non responsive support for Connect360. Rivet also had a few neat features such as auto media updating, and better file organization, both of which appealed to me.

Unfortunately, over the past few months I have become annoyed with the need to constantly restart Rivet in order for it to function properly (both with the 1.x and 2.x versions). This can be caused by:

1. Moving between wireless networks. Once I reconnect to my home network, the Xbox won't detect my MBP until Rivet is restarted.

2. Sleeping. Once the MBP has been woken up in the morning, Rivet must again be restarted.

3. Occasionally, Rivet also stops working when new movies are added to one of my shared folders. This I can't explain.

It has come to a point where 50% of the time when I want to use Rivet, it needs to be restarted before anything will work properly.

Although Connect360 lacks a few features, it is ROCK SOLID on the network side. As long as the MacBook Pro is turned on and connected to my wireless network, it always works! No fiddling required.

If you have a desktop computer, definitely get Rivet. But when it comes to a laptop and network connectivity, Connect360 just can't be beat.

ZAPH47  This app does exactly as described and works great. Rivet does a much better job than the rarely updated Connect360 managing your media as you have it setup without the user accommodating the app. Though 2.0 wasn't a major update for XBOX360 users, it's still a sigh of relief to see the developers are actually continuously working on it...A+

BLAFUSEL  This is a great app. It does exactly what I was looking for. Recommended over Connect 360.

TOURNESOL  Works great! To bad Xbox 360 wont recognize any video formats at all.

REVCO  Why is Rivet's interface identical to Connect360? Did you have anything to do with Connect360?

JOBBY  Looks good, but a couple of nits:

If you have a load of playlists in iTunes, and you're trying to share just a couple, you *really* could do with a "deselect all" button in the Music tab :)

I see "share photos from iPhoto"... but where's "share photos from Aperture"? I don't want to have to export all my photos just so my 360 can see them (one copy of each is quite enough to have lying around)

XPANDER  I got in on the beta for this app and it totally demolishes the competition (Connect360). It allows you to share multiple folders, and I'm not plagued by Connect360 pegging both my cpu's for no reason. If you are considering connect360, do yourself a favor and get this instead. Great app.
