Playing RMVB files Issue

[Harry Muscle]

I'm running XBMC for Windows 9.04.1 r20672 and I'm running into an issue whenever I try to play RMVB files. From what I can tell, XBMC tries to read the whole RMVB file before it starts playing it. It's no big deal when the file is stored on the same machine since reading the whole file is quick then, but when a large RMVB file is stored on a network drive (especially wireless network), it can sometimes take 10 minutes before the file starts to play. I've attached a sample log file, showing a 180MB RMVB file being playing over a 100Mbit connection. From the log file the delay is a bit over 20 seconds. However, on my production setup, I have a wireless connection, so the delay for just this file is probably around double that. And the delay for my 700MB files is crazy long.

Before I put together a bug report I just wanted to find out if this is a known issue, etc.

My log file: EDIT: see below ...

Thanks

EDIT: Didn't realize there's logs and then there's debug logs :)

So here's the full debug log of me trying to play a RMVB file over a wireless conection using my HTPC: http://pastebin.com/f54e8b678
