I might have to try reformatting my PC because I've never had this connection problem before.  Everytime I try to play a WTV files through my Xbox 360 extender via wireless G (yes I play HD files but never have lag luckily), I get disconnected all the time.  Mind you, this is only WTV files that are recorded from TV.  I have plenty of WTV files containing h.264 that I converted from MKV that never drop, and these are a high bitrate too.

If I convert the files to MPG and play them through the videos folder, everything is fine.  So this is a bit confusing because the problem seems limited to WTV files encoded with MPG.

Bumping this up, I've never been able to really find out what the issue is.

 I'm running Windows 7 Ultimate and use my Xbox 360 as an extender and seem to drop WTV files all the time.  Thought it was maybe wireless, but its happening in wired connection too. 

My computer is home built using:

 Gigabyte GA-P35c-DS3R, 4gb RAM, Intel Q9450 Quad processor, Aver Duet Tv Tuner, 2x Western Digital 1TB hard drives.

All this is wired to a Linksys WRT54GL v 1.1        

The linksys is using the most current build of dd-wrt (any firmware hasn't mattered)

It used to be just dropping WTV with mpg, now even higher bitrate MKV's that normally would play won't go through.  Is this connection issue common?

I've read little odds and ends about turning on "flow control" and other stuff in the NIC properties.  Mine seemed to be enabled by default, anything else in the NIC or the router I might want to fiddle with?

 Any help is awesome guys, I would really appreciate it.
