Cheap disc's which should work okay are the b-brands of Taiyo Yuden.
Most times these are named. Sentinel, Parrot(16x/24x), Taibotech, That's (not the same as That's write)
Any disc made by Taiyo Yuden will state Japan as country in which it was made.
Also sometimes Fuji can be bought very cheap and also Fuji uses TY allong with there own disc's. (Made in Japan fuji's are the TY's)
Any disc from Taiyo Yuden or Mitsui will work correct with a Philips burner that is my experience. Mitsui really works very good with them. The only problem is that most compannies use TY or Mitsui are manufacturer do not sell there disc's cheap.
TDK have used the following manufacturers:
Sony has used the following manufacturers:
Imation is also made by CMC and are very poor disc's.
