[ale] Digital VCR

[Dow Hurst]

Can you guarantee that you can write 27Mb/s continuously for an hour? 
What type drives and bus are you using?  You might need to tailor your
machine some so other processes won't interfere.  Under IRIX you can
assign a portion of the CPU to a task, can you do this under Linux? 
Also, will 95Gbs raw compress down to a DVD in the current DVD format? 
I don't know much about DVD except that you would need to get below 5Gb,
right?
