Hi,

There are some differences with the video engine between the AST2400 and 
AST2500 that I haven't addressed yet, so probably the driver is not 
working correctly on the AST2400 yet. Some registers have different bit 
mapping, and things like that. Sorry about that... thanks for trying it 
out! I'll look at the changes needed for AST2400 next.

Thanks,

Eddie
