Unexplainable Mame slowdown through a TV

[Tripplejol]

Hello All,

My apologies if this seems to come out of the blue, but I'm pulling my hair out at the minute. I'm trying making a portable multi-emulator system out of a PC.

The PC has a 128MB ATI Radeon X1300 & The software I'm running is Mame .115, ZSnes & VisualBoyAdvance through Mamewah 1.62b3. on XP Home.
During the testing & setup stages I've been running the PC through a standard LCD monitor & there have been no problems in the gamespeed.

But when I run the system through the home TV (S-VHS to Phono, yes I know. Bad quality) I experience slowdown on Mame games, even real oldies like Pacman.

What's even more puzzling is that the same problem is occurring with VisualBoyAdvance through the TV (even with classic GameBoy games). However ZSnes runs fine regardless.

Needless to say the whole experience has left me entirely .

I have no idea whether this is something that can be overcome by simply changing the settings or whatever... If anyone has any ideas on how to overcome this, it would be greatly appreciated.

Although this is just a shot in the dark, ensure that the card is inserted completely into the AGP slot (assuming AGP).  I had a similar experience (although my slowdown was universal) with a Radeon card where it wasn't properly seated in the slot.

Are you testing with both the tv and LCD monitor attached at the same time?

If so, try disconnected the LCD and booting with just the TV attached (your radeon should autodetect the connected TV at boot).

Thanks for the support guys, but I solved it. After much tooling around I found the answer to be something embarassingly terrestrial, I just switched triple buffering off & everything runs fine... Is that a common problem or is my TV just too much of a throwback?

All I've got to do now is find a way round the tearing...
