No Time Search for SVCD's on Pioneer XV-HTD1???

[idoc]

I burned SVCD's (NTSC) and they play without any problem on my DVD player. I can scan forward and backward. The only thing I can't do is do a Time Search of the disc. Only the Track Search option comes up when I try. Thus, I have to scan forward until I reach the part that I want to view. I don't have this problem with VCD's (original and burnt) where the Time Search option is displayed after the Track Search option. This makes scanning of my SVCD's (videocam archives) very tedious. Don't know if this is an authoring, burning, or player issue. Any ideas?

My set-up:
ULead Video Studio 5.0
Nero 5.5.1.9
Yamaha CRW 2100E 16/10/40
Imation CD-R 80min (same result with Kodak CD-RW)
Pioneer XV-HTD1 DVD Receiver (XV-HTD510 in other
countries)

Can anybody please offer any help or ideas? I've seen this problem posted about 2x in the past but there had been no solutions suggested. Thanks
