Yep. All of these problems don't seem to be related to the recordings, 
as i have 3 other frontends that display them fine.

Not really.  All nvidia cards. The 64 machine is a fx5300 (same as 5200 
except PCIe).  HD frontend is athlon xp-3200, with fx5200. slave 
backend is pentium 4 - 2.4 with nvidia fx 5200. I also have a laptop 
with pentium M 1.3 with ati. The 64 machine is the only one to 
experience *any* video problems. I know that there was some work in 
regards to the mmx-assembly in the code. I vaguely remember someone 
else in the mailing list reporting issues with bob on an 64. My other 
problem concerns me more, since there is no real workaround. Except 
watch things on the frontend upstairs ;) Has anyone else experienced 
anything like it? [See inital message in thread for description of that
