Gentlemen (and possibly ladies) I have the same problem i get the whole toc edit and it erases discs. there is something with the record head but unfortunately my warranty is devoid and to make it worse i am in africa. it is going to cost me an arm , a leg and a right testicle. I already gave away the left testicle to get the damn thing.
Sony is not being a fair player in these stupid net md things. To think i passed up the first generation ipods for this heap of crud.
I am the dismayed owner of the Mz-505 ......
