Forgive me to ask stupid question;
if I used render and burn into dics manual in vf- mpeg2, vt- blu-ray1440x1080-50i, 25 mdps.
Do I HAVE to use a blu-ray dic to burn? I been using dvd to burn this format and it took me 8 hours to do it, does it normal for such long hours?

I did try to burn into avchd in 25 min footage but it doesn't work and I tried to reduced it to a 5 min footage then it work.

cheers
