Just last week I bought a Sony HDR-HC3E (that last E makes it more expensive - PAL) for 1150 euro's, a reasonable deal. It's a reasonably compact nicely designed 1080i camcorder. I plan to use it for point and shoot. I'm still using my two year old Acer laptop (A64 3000+ DTR) though and for the first time it is a bit slow. Regards, Rink

Dear Gzubeck: Sorry to tell you this, but higher bit rates means less decode cycles are needed. The less compression, the easier it gets. What is likely happening is that the stream is encrypted and it needs to be decrypted on the fly. Decryption is far faster using 64 bit codes. So using Win XP 32 bit is not using any AMD64 capable CPU to its fullest. Going to Win XP64 Pro is likely to reduce CPU usage by 2-3 times. Thus a single A64 3500+ running 64 bit would be more than fast enough to decode VC-1 on XP64 for 1920x1080p unless its doing something rotten (MPAA would do something like that as they would shoot their own leg to get more money). Yes under Linux 64, mplayer takes about half as much (20 to 30% CPU) to decode the .ts 1920x1080i stream as it does under i86 Linux. Pete
