I am playing WMA lossless (9.2), so the bitrate is higher than what a lot of people typically use, and that might be a factor of the playback. They are streaming off a 7200 RPM WD Caviar Black Ed. , so no speed problem there.
AMD Dual Core, so that isn't a problem.
Windows Vista Ultimate x64.
I have Full 100% Wireless G 54mbps signal on both the host computer and Xbox.
Thanks for getting back to me, I'd like to think I have a lot of experience with this streaming stuff up to the point of the internals and writing of the software, so I'd be glad to help you with admin if you need it.
No problem... let's figure this out.

Your specs certainly appear to be more than adequate; nonetheless, if you could check your CPU utilization while playing one of those WMA Lossless tracks to the 360, that would be a good start. On a Dual Core you're looking to see how close you are to 50% CPU on the jamcastsvc.exe process (it will only use 1 core).
My wireless network probably performs less than yours as I have a couple of B devices on it, and the 360 signal is low... not to mention the fact that my neighborhood has alot of wifi in range. To be thorough, if it's possible, you could try running the PC and Xbox360 wired. Sounds like that's probably a huge pain for you, but it would be useful to at least rule out the network for sure.
I'm going to take a real close look at WMA Lossless to the 360 on my end as well; last time I checked I had no problems with any of my content to the 360, but I want to observe CPU utilization and see if there's additional performance I can get.
FWIW, everything except WMA is transcoded (when necessary, of course) via FFMpeg, which runs in a seperate process and is extremely efficient. However, I use the built-in Windows Media libraries for WMA because the codec support is much more comprehensive, but these libraries are a bit heavy on resources. WMA Lossless does transcode to the 360 as uncompressed, lossless LPCM audio, with sample rate/bitrate/etc. maxed out according to the source track and capabilities of the 360 (max 48kHz 24bit stereo). FYI these are the same libraries that WMP would use for trancoding WMA Lossless to the 360.
Get back to me when you can, and I'll follow up when I've taken a close look at WMA transcoding to see if I've got any work to do there.
Thanks!
