I would try that too! Have suspicions that I have with 10.0.5 have more buffers with 720p. Hope the build of user Keith will solve the problem.

I just tried the latest nightly build and I have the same amount of buffering with SMB shares.

Uhmzz... hope there will be soon a smb fix. Or the option to scraping via uPnP

Have you guys tried hardwiring your connection just to see if its a wireless issue....
Remember that you only can pretty much only get the highest advertised speed of your wireless about 4 inches away from the wireless device... the farther away you get the slower your speed.....
I used to have these issues all the time on my Windows based XBMC... over wireless N i would get stuttering and buffering on any file over about 4-5GB...... I finally was able to wire cat5e behind my tv and now the exact same machine plugged in with GB ethernet has played everything over the network I could throw at it.... the biggest file I have is my Bluray rip of Avatar which is 40GB mkv file (i ripped it with Makemkv)
I've also done some other testing with this machine on slower speeds. I switched the interface down to 100Mb and at this setting it seems like files over 20GB will stutter ever so often. I have also confirmed this with my Asus Oplay which only has 100Mb wired ethernet.. it seems to start stuttering on files over 20GB also. With that being said I would think the AppleTV2 hardwired (100Mb) should be able to play a 20GB H.264 file over the network. I do not own one though so I cannot confirm.
I do hope to get one soon. I think the device would be much nicer in my bedroom than my roku box.

My issue is that I can stream higher bitrate, larger files through frontrow and iTunes just fine. That seems to contradict the wireless bandwidth theory.
I have tested the same file in 720p mkv and then repackaged into m4v with mkvtools so it can stream through iTunes. The mkv through xbmc buffered 3-4 times in the 40 min file length. The m4v through iTunes never buffered, and was fully loaded into the atv before it was even half over.
Mkv tools does not reencode, so the bitrate didnt change. Only the container.

Exactly, if I use UPnP I can stream 1080p .mkvs on the ATV2 with no buffering.
Also, if I use XBMC on my laptop, I can stream the same 1080p .mkvs via SMB with no buffering.
Something is up with the SMB protocol on XBMC ATV2.

My atv2 is hard wired to my router. I have 2 Buffalo nas drives. Both connected using SMB.
I'm having problems with xvid 720p movies. 720 h.264, 1080 h264 and 480 xvid films work fine.
720p xvid are playing perfectly fine over wireless on my Macbook Pro using SMB with VLC (not tried xbmc yet)! but trying to play on the ATV2 via wired they buffer every few seconds.
I tried connecting via uPNP and it was a little better...perhaps buffering every 8 seconds instead of 2.
...but I can stream 1080p & 720 h.264 with DTS5.1 sound track without any problems at all. So perhaps a bug with 720p xvid?

yep, I'm pretty certain it's that combination of 720 and xvid. I've got a number of files formatted in that way and it does it on all of them...but none of the h264.
Where do I need to go to log a bug?

From the current issues sticky:
"Hardware decoding is for h264 only. As a result, 720p XviD, WMV and other HD encodings stutter. Standard definition should work fine."
