iMac DVD Player and memory: a follow-up

Confirming what we had noted previously, Patrick Pell-Richards found that problems he had playing DVD movies on his new iMac were alleviated by upping the iMac's memory to 128MB. The reason this extra memory is needed may relate to what Patrick found when he checked the About This Computer window:

"Before adding the extra RAM, I went to About This Computer with the DVD Player on and noticed that the Mac OS memory allocation jumped from 20MB to 50MB! The DVD Player had only 13MB or so and the largest unused block was 388K. I quit the DVD Player and the Mac OS memory went back to 20MB."

Michel Yves Dufresne reports a similar finding. Virtual Memory was off at the time.
