SageTV Client issues

[Steerpike]

I'm running the SageTV client over a wireless (802.11g) network. I've been mainly using it to setup recordings, but recently I've been using the client to watch recorded shows.

I've noticed the playback is not at all smooth. It's not so much that frames are dropped, but rather, scrambled perhaps? It's as if some frames are getting ahead of others maybe.

Anyway, not wanting to blame Sage Client for this, I viewed the same recorded show using WinDVD, over the same network; playback is very smooth (both Sage and WinDVD get the occasional stutter due to wireless dropout, and I can accept that).

I'm using windows XP Pro, and have the task manager / Networking tab open, and can view network utilization; it hovers around 20%. If, by comparison, I copy a massive video file over the wireless network, utilization goes up to around 50%. CPU utilization is low, by the way (under 50%) in either case. Also, when copying massive files (4GBytes), I get a measured bitrate of about 20 Megabits per second, which is above the required data rate.

So basically, winDVD plays a given file much better than Sage Client. Is this a known issue, and can anything be done? One thought I had was, can the amount of data buffered by the client be increased? Since my overall throughput is adequate, could it be the Sage client is not buffering enough data to accomodate minor glitches?

Thanks!
