Samsung YP-Q1 CB PMP

[virus000]

Hi,i recently purchased a Samsung YP-Q1 media player and loaded some vids and mp3's to it.It comes with 8gb of space which i filled up with 4-5gb of small vids and say 1gb of mp3.Now it doesnt seem to take videos any more when it still has 3 gb of free space??It converts an avi/wmv to svi format with its Emodio software.so if i drag and drop to it ,it used to show the file which now it doesnt.so i dont understand where the prob is??
im having trouble to find games to download to player which come in .xov format.i googled and couldnt find anything.So if samsung's players or gadgets apps are hard to find,im having second thoughts on buying a corby pro phone which i may be unable to find apps/games??is the decision right??
