Hi, Im toying with the idea of building a PC based audio visual centre after my flat mate took the DVD player and TV with him when he left. Im excited about the possiblity of a fan-less mini-itx based motherboard or even would consider a micro-atx if the extra power justifies. I have a couple of concerns namely regards the next generation DVD and the ability of current PC hardware to handle the throughput of such a medium. I understand I can upgrade the DVD drive when Blu-Ray or HD Dvd comes out but what about the SATA/IDE interfaces, the 800Mhz/1Ghz processor or even the memory bandwidth of say PC3200, will these be able to handle such an extra workload? Or am I likely going to be ending replacing most of the PC? The other issue Im not to convinced about is whether, in terms of visual quality, DVD playing software on a standard DVD drive can compete with a decent dedicated DVD player with all that supporting hardware ?
