Hi, I'm getting frustrated with my Nokia N800 and I hope someone can help me. I bought this for a couple reasons, the 2 big ones are for SIP video calling and for playing videos off my MythTV. I have been totally unsuccessful so far. The media player finds my MythTV server, but it refuses to play any videos. It turns out that the videos are stored in standard definition format, which the Nokia can't play. Why do they advertise it's video capabilities if it can't play standard videos? I'm using a WinTV PVR-500 to record MPEG-4 videos. They play great on my Linux desktop and my Windows laptop, but they refuse to play on my N800, even though Nokia advertises that it plays MPEG-4. Can anyone help? I've tried transcoding files to flash, but they look awful and are very choppy. Not watchable. I also tried transcoding down to a lower resolution with similar problems. At least they play, but what good is a 800x600 screen if the videos have to be 288x160? And, even then, the fast forward doesn't work and it regularly hangs and the video and audio doesn't sync. One big features that Nokia advertises is the ability to do video conferencing. Can someone tell me how to set it up so I can conference from my Nokia to my Linux desktop machine? Apparently, you have to use the Nokia Internet Calling Invitation software, which isn't ported to Linux. I tried the Windows version on my laptop but it refused to run until I bought a webcam. There's no support for one-way video with two-way audio? And, no support for Linux? *sheesh* Beyond that, I can't seem to get a normal SIP voice client at all. Tapioca doesn't support SIP. Minisip supposedly works, but the repository is down. Gizmo supports SIP, but only if you have a Gizmo account. I'm using Allo.com. Can someone please, please tell me where to get a SIP client? Is anyone out there having any success with their N800? So far, I've paid $400 for a brick I can play "pipe panic" on. Why does this get such great reviews? -Dave
